+
+	* linuxthreads.texi: Updated pthread_atfork documentation to make
+	it clear that fork and pthread_atfork can't be reentered from
+	atfork handlers, that pthread_atfork and fork are mutually atomic,

+	is waiting for all other threads to die, send a REQ_KICK into

+Release 0.9:
+- more ports (SH, IA-64, s390)
+- many bug fixes
+- timed sync object wait functions
+- barrier implementation
+- spinlocks implementation
+- thread register on x86
+- variable stack size and position on some platforms
+
+Release 0.8:
+(ehmm, forgot to update, don't know anymore)
+
+Release 0.7:
+- Destructors for thread-specific data now conform to the POSIX semantics
+  (call destructors again if non-NULL TSD remains after a round of
+   destruction).
+- Implemented thread-specific data as a sparse array, allows more TSD keys
+  and smaller thread descriptors (Ulrich Drepper).
+- Added "error checking" mutexes.
+- Protect against multiple sigwait() on the same signals.
+- Simplified implementation of semaphores when compare_and_swap is
+  not available.
+- Fixed bug in fork() where stdin was closed if fork() was called before
+  the first pthread_create().
+- Fixed bug in the gethostby*_r functions (bad result if null bytes
+  in addresses).
+- Typos in manual pages corrected.
+- First cut at a PowerPC port (not working yet, runs into problems
+  with gcc and with the C library).
+
+Release 0.6:
+- Validation of thread identifiers: no more crashes when operating on
+  a thread that has exited (based on Pavel Krauz's ideas).
+- Added fallback implementation of semaphores for the 386 and the
+  Sparc.
+- Fixed a bug in signal handling causing false restarts of suspended
+  threads.
+- Fixed a bug in realtime scheduling causing all threads to have
+  default scheduling on Ix86 with libc5.
+- With realtime scheduling, unlocking a mutex now restarts the
+  highest priority thread waiting on the mutex, not the
+  first-suspended thread (Richard Neitzel).
+- Timing a process now returns cumulative times for all threads, not
+  just times for the initial thread (suggested by Wolfram Gloger).
+- Cleaned up name space (internal defs prefixed by __, weak aliases
+  for non-portable extensions).
+- MIPS port (contributed by Ralf Baechle).
+
+Release 0.5:
+- Signal-safe semaphores a la POSIX 1003.1b added.
+- Locking bug in pthread_mutex_trylock over recursive mutexes fixed.
+- Race conditions in thread cancellation fixed.
+- Sparc port (contributed by Miguel de Icaza).
+- Support for getpwnam_r and getpwuid_r.
+- Added pthread_kill_other_threads_np to be used in conjunction with
+  exec*().
+
+Release 0.4:
+- Manual pages for all functions.
+- Synchronization bug causing accumulation of zombie processes fixed.
+- Race condition in pthread_cond_timedwait fixed.
+- Recursive mutexes are back by popular demand.
+- Partial support for realtime scheduling (initiated by Richard Neitzel).
+- pthread.h cleaned up a lot: now C++ compatible, added missing "const"
+  qualifiers, added short documentation, put to GNU libc standards
+  for name space pollution (Ulrich Drepper).
+- Motorola 68k port (contributed by Andreas Schwab).
+- Interaction with fork(2) cleaned up a lot.
+
+Release 0.3:
+- Thread creation and reclaimation now performed by a centralized
+  "thread manager" thread.
+- Removed recursive mutexes to make regular mutexes more efficient.
+- Now available as a shared library (contributed by Richard Henderson).
+- Alpha port (contributed by Richard Henderson).
+- Fixed many small discrepancies with Posix 1003.1c.
+- Put under the LGPL instead of the GPL.
+
+Release 0.2:
+- Reentrant libc functions (adapted from libc 5.3.9 by Peeter Joot)
+- pthread_cond_wait did not reacquire the mutex correctly on return
+- More efficient pthread_cond_broadcast
+
+Release 0.1:
+- First public release

+
+<H4><A NAME="A.1">A.1: What is LinuxThreads?</A></H4>
+
+LinuxThreads is a Linux library for multi-threaded programming.
+It implements the Posix 1003.1c API (Application Programming
+Interface) for threads.  It runs on any Linux system with kernel 2.0.0
+or more recent, and a suitable C library (see section <A HREF="C">C</A>).
+<P>
+
+<H4><A NAME="A.2">A.2: What are threads?</A></H4>
+
+A thread is a sequential flow of control through a program.
+Multi-threaded programming is, thus, a form of parallel programming
+where several threads of control are executing concurrently in the
+program.  All threads execute in the same memory space, and can
+therefore work concurrently on shared data.<P>
+
+Multi-threaded programming differs from Unix-style multi-processing in
+that all threads share the same memory space (and a few other system
+resources, such as file descriptors), instead of running in their own
+memory space as is the case with Unix processes.<P>
+
+Threads are useful for two reasons.  First, they allow a program to
+exploit multi-processor machines: the threads can run in parallel on
+several processors, allowing a single program to divide its work
+between several processors, thus running faster than a single-threaded
+program, which runs on only one processor at a time.  Second, some
+programs are best expressed as several threads of control that
+communicate together, rather than as one big monolithic sequential
+program.  Examples include server programs, overlapping asynchronous
+I/O, and graphical user interfaces.<P>
+
+<H4><A NAME="A.3">A.3: What is POSIX 1003.1c?</A></H4>
+
+It's an API for multi-threaded programming standardized by IEEE as
+part of the POSIX standards.  Most Unix vendors have endorsed the
+POSIX 1003.1c standard.  Implementations of the 1003.1c API are
+already available under Sun Solaris 2.5, Digital Unix 4.0,
+Silicon Graphics IRIX 6, and should soon be available from other
+vendors such as IBM and HP.  More generally, the 1003.1c API is
+replacing relatively quickly the proprietary threads library that were
+developed previously under Unix, such as Mach cthreads, Solaris
+threads, and IRIX sprocs.  Thus, multithreaded programs using the
+1003.1c API are likely to run unchanged on a wide variety of Unix
+platforms.<P>
+
+<H4><A NAME="A.4">A.4: What is the status of LinuxThreads?</A></H4>
+
+LinuxThreads implements almost all of Posix 1003.1c, as well as a few
+extensions.  The only part of LinuxThreads that does not conform yet
+to Posix is signal handling (see section <A HREF="#J">J</A>).  Apart
+from the signal stuff, all the Posix 1003.1c base functionality,
+as well as a number of optional extensions, are provided and conform
+to the standard (to the best of my knowledge).
+The signal stuff is hard to get right, at least without special kernel
+support, and while I'm definitely looking at ways to implement the
+Posix behavior for signals, this might take a long time before it's
+completed.<P>
+
+<H4><A NAME="A.5">A.5: How stable is LinuxThreads?</A></H4>
+
+The basic functionality (thread creation and termination, mutexes,
+conditions, semaphores) is very stable.  Several industrial-strength
+programs, such as the AOL multithreaded Web server, use LinuxThreads
+and seem quite happy about it.  There used to be some rough edges in
+the LinuxThreads / C library interface with libc 5, but glibc 2
+fixes all of those problems and is now the standard C library on major
+Linux distributions (see section <A HREF="#C">C</A>). <P>

+<H2><A NAME="B">B.  Getting more information</A></H2>
+
+<H4><A NAME="B.1">B.1: What are good books and other sources of
+information on POSIX threads?</A></H4>
+
+The FAQ for comp.programming.threads lists several books:
+<A HREF="http://www.serpentine.com/~bos/threads-faq/">http://www.serpentine.com/~bos/threads-faq/</A>.<P>
+
+There are also some online tutorials. Follow the links from the
+LinuxThreads web page:
+<A HREF="http://pauillac.inria.fr/~xleroy/linuxthreads">http://pauillac.inria.fr/~xleroy/linuxthreads</A>.<P>
+
+<H4><A NAME="B.2">B.2: I'd like to be informed of future developments on
+LinuxThreads. Is there a mailing list for this purpose?</A></H4>
+
+I post LinuxThreads-related announcements on the newsgroup
+<A HREF="news:comp.os.linux.announce">comp.os.linux.announce</A>,
+and also on the mailing list
+<code>linux-threads@magenet.com</code>.
+You can subscribe to the latter by writing
+<A HREF="mailto:majordomo@magenet.com">majordomo@magenet.com</A>.<P>
+
+<H4><A NAME="B.3">B.3: What are good places for discussing
+LinuxThreads?</A></H4>
+
+For questions about programming with POSIX threads in general, use
+the newsgroup
+<A HREF="news:comp.programming.threads">comp.programming.threads</A>.
+Be sure you read the
+<A HREF="http://www.serpentine.com/~bos/threads-faq/">FAQ</A>
+for this group before you post.<P>
+
+For Linux-specific questions, use
+<A
+HREF="news:comp.os.linux.development.apps">comp.os.linux.development.apps</A>
+and <A
+HREF="news:comp.os.linux.development.kernel">comp.os.linux.development.kernel</A>.
+The latter is especially appropriate for questions relative to the
+interface between the kernel and LinuxThreads.<P>
+
+<H4><A NAME="B.4">B.4: How should I report a possible bug in
+LinuxThreads?</A></H4>
+
+If you're using glibc 2, the best way by far is to use the
+<code>glibcbug</code> script to mail a bug report to the glibc
+maintainers. <P>
+
+If you're using an older libc, or don't have the <code>glibcbug</code>
+script on your machine, then e-mail me directly
+(<code>Xavier.Leroy@inria.fr</code>).  <P>
+
+In both cases, before sending the bug report, make sure that it is not 
+addressed already in this FAQ.  Also, try to send a short program that
+reproduces the weird behavior you observed. <P>
+
+<H4><A NAME="B.5">B.5: I'd like to read the POSIX 1003.1c standard. Is
+it available online?</A></H4>
+
+Unfortunately, no.  POSIX standards are copyrighted by IEEE, and
+IEEE does not distribute them freely.  You can buy paper copies from
+IEEE, but the price is fairly high ($120 or so). If you disagree with
+this policy and you're an IEEE member, be sure to let them know.<P>
+
+On the other hand, you probably don't want to read the standard.  It's
+very hard to read, written in standard-ese, and targeted to
+implementors who already know threads inside-out.  A good book on
+POSIX threads provides the same information in a much more readable form.
+I can personally recommend Dave Butenhof's book, <CITE>Programming
+with POSIX threads</CITE> (Addison-Wesley). Butenhof was part of the
+POSIX committee and also designed the Digital Unix implementations of
+POSIX threads, and it shows.<P>
+
+Another good source of information is the X/Open Group Single Unix
+specification which is available both
+<A HREF="http://www.rdg.opengroup.org/onlinepubs/7908799/index.html">on-line</A>
+and as a
+<A HREF="http://www.UNIX-systems.org/gosolo2/">book and CD/ROM</A>.
+That specification includes pretty much all the POSIX standards,
+including 1003.1c, with some extensions and clarifications.<P>
+
+<HR>
+<P>
+
+<H2><A NAME="C">C.  Issues related to the C library</A></H2>
+
+<H4><A NAME="C.1">C.1: Which version of the C library should I use
+with LinuxThreads?</A></H4>
+
+The best choice by far is glibc 2, a.k.a. libc 6.  It offers very good
+support for multi-threading, and LinuxThreads has been closely
+integrated with glibc 2.  The glibc 2 distribution contains the
+sources of a specially adapted version of LinuxThreads.<P>
+
+glibc 2 comes preinstalled as the default C library on several Linux
+distributions, such as RedHat 5 and up, and Debian 2.
+Those distributions include the version of LinuxThreads matching
+glibc 2.<P>
+
+<H4><A NAME="C.2">C.2: My system has libc 5 preinstalled, not glibc
+2.  Can I still use LinuxThreads?</H4>
+
+Yes, but you're likely to run into some problems, as libc 5 only
+offers minimal support for threads and contains some bugs that affect
+multithreaded programs. <P>
+
+The versions of libc 5 that work best with LinuxThreads are
+libc 5.2.18 on the one hand, and libc 5.4.12 or later on the other hand.
+Avoid 5.3.12 and 5.4.7: these have problems with the per-thread errno
+variable. <P>
+
+<H4><A NAME="C.3">C.3: So, should I switch to glibc 2, or stay with a
+recent libc 5?</A></H4>
+
+I'd recommend you switch to glibc 2.  Even for single-threaded
+programs, glibc 2 is more solid and more standard-conformant than libc
+5.  And the shortcomings of libc 5 almost preclude any serious
+multi-threaded programming.<P>
+
+Switching an already installed
+system from libc 5 to glibc 2 is not completely straightforward.
+See the <A HREF="http://sunsite.unc.edu/LDP/HOWTO/Glibc2-HOWTO.html">Glibc2
+HOWTO</A> for more information.  Much easier is (re-)installing a
+Linux distribution based on glibc 2, such as RedHat 6.<P>
+
+<H4><A NAME="C.4">C.4: Where can I find glibc 2 and the version of
+LinuxThreads that goes with it?</A></H4>
+
+On <code>prep.ai.mit.edu</code> and its many, many mirrors around the world.
+See <A
+HREF="http://www.gnu.org/order/ftp.html">http://www.gnu.org/order/ftp.html</A>
+for a list of mirrors.<P>
+
+<H4><A NAME="C.5">C.5: Where can I find libc 5 and the version of
+LinuxThreads that goes with it?</A></H4>
+
+For libc 5, see <A HREF="ftp://sunsite.unc.edu/pub/Linux/devel/GCC/"><code>ftp://sunsite.unc.edu/pub/Linux/devel/GCC/</code></A>.<P>
+
+For the libc 5 version of LinuxThreads, see
+<A HREF="ftp://ftp.inria.fr/INRIA/Projects/cristal/Xavier.Leroy/linuxthreads/">ftp://ftp.inria.fr/INRIA/Projects/cristal/Xavier.Leroy/linuxthreads/</A>.<P>
+
+<H4><A NAME="C.6">C.6: How can I recompile the glibc 2 version of the
+LinuxThreads sources?</A></H4>
+
+You must transfer the whole glibc sources, then drop the LinuxThreads
+sources in the <code>linuxthreads/</code> subdirectory, then recompile
+glibc as a whole.  There are now too many inter-dependencies between
+LinuxThreads and glibc 2 to allow separate re-compilation of LinuxThreads.
+<P>
+
+<H4><A NAME="C.7">C.7: What is the correspondence between LinuxThreads 
+version numbers, libc version numbers, and RedHat version
+numbers?</A></H4>

+
+<H4><A NAME="D.1">D.1: When I compile LinuxThreads, I run into problems in
+file <code>libc_r/dirent.c</code></A></H4>
+
+You probably mean:
+<PRE>
+        libc_r/dirent.c:94: structure has no member named `dd_lock'
+</PRE>
+I haven't actually seen this problem, but several users reported it.
+My understanding is that something is wrong in the include files of
+your Linux installation (<code>/usr/include/*</code>). Make sure
+you're using a supported version of the libc 5 library. (See question <A
+HREF="#C.2">C.2</A>).<P>
+
+<H4><A NAME="D.2">D.2: When I compile LinuxThreads, I run into problems with
+<CODE>/usr/include/sched.h</CODE>: there are several occurrences of
+<CODE>_p</CODE> that the C compiler does not understand</A></H4>
+
+Yes, <CODE>/usr/include/sched.h</CODE> that comes with libc 5.3.12 is broken.
+Replace it with the <code>sched.h</code> file contained in the
+LinuxThreads distribution.  But really you should not be using libc
+5.3.12 with LinuxThreads! (See question <A HREF="#C.2">C.1</A>.)<P>
+
+<H4><A NAME="D.3">D.3: My program does <CODE>fdopen()</CODE> on a file
+descriptor opened on a pipe.  When I link it with LinuxThreads,
+<CODE>fdopen()</CODE> always returns NULL!</A></H4>
+
+You're using one of the buggy versions of libc (5.3.12, 5.4.7., etc).
+See question <A HREF="#C.1">C.1</A> above.<P>
+
+<H4><A NAME="D.4">D.4: My program creates a lot of threads, and after
+a while <CODE>pthread_create()</CODE> no longer returns!</A></H4>
+
+This is known bug in the version of LinuxThreads that comes with glibc
+2.1.1.  An upgrade to 2.1.2 is recommended. <P>
+
+<H4><A NAME="D.5">D.5: When I'm running a program that creates N
+threads, <code>top</code> or <code>ps</code>
+display N+2 processes that are running my program. What do all these
+processes correspond to?</A></H4>
+
+Due to the general "one process per thread" model, there's one process
+for the initial thread and N processes for the threads it created
+using <CODE>pthread_create</CODE>.  That leaves one process
+unaccounted for.  That extra process corresponds to the "thread
+manager" thread, a thread created internally by LinuxThreads to handle
+thread creation and thread termination.  This extra thread is asleep
+most of the time.
+
+<H4><A NAME="D.6">D.6: Scheduling seems to be very unfair when there
+is strong contention on a mutex: instead of giving the mutex to each
+thread in turn, it seems that it's almost always the same thread that
+gets the mutex. Isn't this completely broken behavior?</A></H4>
+
+That behavior has mostly disappeared in recent releases of
+LinuxThreads (version 0.8 and up).  It was fairly common in older
+releases, though.
+
+What happens in LinuxThreads 0.7 and before is the following: when a
+thread unlocks a mutex, all other threads that were waiting on the
+mutex are sent a signal which makes them runnable.  However, the
+kernel scheduler may or may not restart them immediately.  If the
+thread that unlocked the mutex tries to lock it again immediately
+afterwards, it is likely that it will succeed, because the threads
+haven't yet restarted.  This results in an apparently very unfair
+behavior, when the same thread repeatedly locks and unlocks the mutex,
+while other threads can't lock the mutex.<P>
+
+In LinuxThreads 0.8 and up, <code>pthread_unlock</code> restarts only
+one waiting thread, and pre-assign the mutex to that thread.  Hence,
+if the thread that unlocked the mutex tries to lock it again
+immediately, it will block until other waiting threads have had a
+chance to lock and unlock the mutex.  This results in much fairer
+scheduling.<P>
+
+Notice however that even the old "unfair" behavior is perfectly
+acceptable with respect to the POSIX standard: for the default
+scheduling policy, POSIX makes no guarantees of fairness, such as "the
+thread waiting for the mutex for the longest time always acquires it
+first".  Properly written multithreaded code avoids that kind of heavy
+contention on mutexes, and does not run into fairness problems.  If
+you need scheduling guarantees, you should consider using the
+real-time scheduling policies <code>SCHED_RR</code> and
+<code>SCHED_FIFO</code>, which have precisely defined scheduling
+behaviors. <P>
+
+<H4><A NAME="D.7">D.7: I have a simple test program with two threads
+that do nothing but <CODE>printf()</CODE> in tight loops, and from the
+printout it seems that only one thread is running, the other doesn't
+print anything!</A></H4>
+
+Again, this behavior is characteristic of old releases of LinuxThreads
+(0.7 and before); more recent versions (0.8 and up) should not exhibit
+this behavior.<P>
+
+The reason for this behavior is explained in
+question <A HREF="#D.6">D.6</A> above: <CODE>printf()</CODE> performs
+locking on <CODE>stdout</CODE>, and thus your two threads contend very
+heavily for the mutex associated with <CODE>stdout</CODE>.  But if you
+do some real work between two calls to <CODE>printf()</CODE>, you'll
+see that scheduling becomes much smoother.<P>
+
+<H4><A NAME="D.8">D.8: I've looked at <code>&lt;pthread.h&gt;</code>
+and there seems to be a gross error in the <code>pthread_cleanup_push</code>
+macro: it opens a block with <code>{</code> but does not close it!
+Surely you forgot a <code>}</code> at the end of the macro, right?
+</A></H4>
+
+Nope.  That's the way it should be.  The closing brace is provided by
+the <code>pthread_cleanup_pop</code> macro.  The POSIX standard
+requires <code>pthread_cleanup_push</code> and
+<code>pthread_cleanup_pop</code> to be used in matching pairs, at the
+same level of brace nesting.  This allows
+<code>pthread_cleanup_push</code> to open a block in order to
+stack-allocate some data structure, and
+<code>pthread_cleanup_pop</code> to close that block.  It's ugly, but
+it's the standard way of implementing cleanup handlers.<P>
+
+<H4><A NAME="D.9">D.9: I tried to use real-time threads and my program
+loops like crazy and freezes the whole machine!</A></H4>
+
+Versions of LinuxThreads prior to 0.8 are susceptible to ``livelocks''
+(one thread loops, consuming 100% of the CPU time) in conjunction with
+real-time scheduling.  Since real-time threads and processes have
+higher priority than normal Linux processes, all other processes on
+the machine, including the shell, the X server, etc, cannot run and
+the machine appears frozen.<P>
+
+The problem is fixed in LinuxThreads 0.8.<P>
+
+<H4><A NAME="D.10">D.10: My application needs to create thousands of
+threads, or maybe even more.  Can I do this with
+LinuxThreads?</A></H4>
+
+No.  You're going to run into several hard limits:
+<UL>
+<LI>Each thread, from the kernel's standpoint, is one process.  Stock
+Linux kernels are limited to at most 512 processes for the super-user,
+and half this number for regular users.  This can be changed by
+changing <code>NR_TASKS</code> in <code>include/linux/tasks.h</code>
+and recompiling the kernel.  On the x86 processors at least,
+architectural constraints seem to limit <code>NR_TASKS</code> to 4090
+at most.
+<LI>LinuxThreads contains a table of all active threads.  This table
+has room for 1024 threads at most.  To increase this limit, you must
+change <code>PTHREAD_THREADS_MAX</code> in the LinuxThreads sources
+and recompile.
+<LI>By default, each thread reserves 2M of virtual memory space for
+its stack.  This space is just reserved; actual memory is allocated
+for the stack on demand.  But still, on a 32-bit processor, the total
+virtual memory space available for the stacks is on the order of 1G,
+meaning that more than 500 threads will have a hard time fitting in.
+You can overcome this limitation by moving to a 64-bit platform, or by
+allocating smaller stacks yourself using the <code>setstackaddr</code>
+attribute.
+<LI>Finally, the Linux kernel contains many algorithms that run in
+time proportional to the number of process table entries.  Increasing
+this number drastically will slow down the kernel operations
+noticeably.
+</UL>
+(Other POSIX threads libraries have similar limitations, by the way.)
+For all those reasons, you'd better restructure your application so
+that it doesn't need more than, say, 100 threads.  For instance,
+in the case of a multithreaded server, instead of creating a new
+thread for each connection, maintain a fixed-size pool of worker
+threads that pick incoming connection requests from a queue.<P>

+
+<H4><A NAME="E.1">E.1: Where is <CODE>pthread_yield()</CODE> ? How
+comes LinuxThreads does not implement it?</A></H4>
+
+Because it's not part of the (final) POSIX 1003.1c standard.
+Several drafts of the standard contained <CODE>pthread_yield()</CODE>,
+but then the POSIX guys discovered it was redundant with
+<CODE>sched_yield()</CODE> and dropped it.  So, just use
+<CODE>sched_yield()</CODE> instead.
+
+<H4><A NAME="E.2">E.2: I've found some type errors in
+<code>&lt;pthread.h&gt;</code>.
+For instance, the second argument to <CODE>pthread_create()</CODE>
+should be a <CODE>pthread_attr_t</CODE>, not a
+<CODE>pthread_attr_t *</CODE>. Also, didn't you forget to declare
+<CODE>pthread_attr_default</CODE>?</A></H4>
+
+No, I didn't.  What you're describing is draft 4 of the POSIX
+standard, which is used in OSF DCE threads.  LinuxThreads conforms to the
+final standard.  Even though the functions have the same names as in
+draft 4 and DCE, their calling conventions are slightly different.  In
+particular, attributes are passed by reference, not by value, and
+default attributes are denoted by the NULL pointer.  Since draft 4/DCE
+will eventually disappear, you'd better port your program to use the
+standard interface.<P>
+
+<H4><A NAME="E.3">E.3: I'm porting an application from Solaris and I
+have to rename all thread functions from <code>thr_blah</code> to
+<CODE>pthread_blah</CODE>.  This is very annoying.  Why did you change
+all the function names?</A></H4>
+
+POSIX did it.  The <code>thr_*</code> functions correspond to Solaris
+threads, an older thread interface that you'll find only under
+Solaris.  The <CODE>pthread_*</CODE> functions correspond to POSIX
+threads, an international standard available for many, many platforms.
+Even Solaris 2.5 and later support the POSIX threads interface.  So,

+
+The POSIX standard provides <B>no</B> mechanism by which a thread A can
+suspend the execution of another thread B, without cooperation from B.
+The only way to implement a suspend/restart mechanism is to have B
+check periodically some global variable for a suspend request
+and then suspend itself on a condition variable, which another thread
+can signal later to restart B.<P>
+
+Notice that <CODE>thr_suspend()</CODE> is inherently dangerous and
+prone to race conditions.  For one thing, there is no control on where
+the target thread stops: it can very well be stopped in the middle of
+a critical section, while holding mutexes.  Also, there is no
+guarantee on when the target thread will actually stop.  For these
+reasons, you'd be much better off using mutexes and conditions
+instead.  The only situations that really require the ability to
+suspend a thread are debuggers and some kind of garbage collectors.<P>
+
+If you really must suspend a thread in LinuxThreads, you can send it a

+Beware, this is specific to LinuxThreads and entirely non-portable.
+Indeed, a truly conforming POSIX threads implementation will stop all

+
+With a "one-to-one" model, as in LinuxThreads (one kernel execution

+<P>
+The reason why this does not work in LinuxThreads is that mutexes,

+
+It affects include files in three ways:
+<UL>
+<LI> The include files define prototypes for the reentrant variants of
+some of the standard library functions,
+e.g. <CODE>gethostbyname_r()</CODE> as a reentrant equivalent to
+<CODE>gethostbyname()</CODE>.<P>
+
+<LI> If <CODE>_REENTRANT</CODE> is defined, some
+<code>&lt;stdio.h&gt;</code> functions are no longer defined as macros,
+e.g. <CODE>getc()</CODE> and <CODE>putc()</CODE>. In a multithreaded
+program, stdio functions require additional locking, which the macros
+don't perform, so we must call functions instead.<P>
+
+<LI> More importantly, <code>&lt;errno.h&gt;</code> redefines errno when
+<CODE>_REENTRANT</CODE> is
+defined, so that errno refers to the thread-specific errno location
+rather than the global errno variable.  This is achieved by the
+following <code>#define</code> in <code>&lt;errno.h&gt;</code>:
+<PRE>
+        #define errno (*(__errno_location()))
+</PRE>
+which causes each reference to errno to call the
+<CODE>__errno_location()</CODE> function for obtaining the location
+where error codes are stored.  libc provides a default definition of
+<CODE>__errno_location()</CODE> that always returns
+<code>&errno</code> (the address of the global errno variable). Thus,
+for programs not linked with LinuxThreads, defining
+<CODE>_REENTRANT</CODE> makes no difference w.r.t. errno processing.
+But LinuxThreads redefines <CODE>__errno_location()</CODE> to return a
+location in the thread descriptor reserved for holding the current
+value of errno for the calling thread.  Thus, each thread operates on
+a different errno location.

+
+Lots of trouble.  If the code uses <CODE>getc()</CODE> or

+in the location pointed to by <CODE>__errno_location()</CODE>, which
+is the thread-local errno variable.  Then, the code above sees that
+<CODE>read()</CODE> returns -1 and looks up errno.  Since

+
+<H4><A NAME="H.4">H.4: With LinuxThreads, I can no longer use the signals
+<code>SIGUSR1</code> and <code>SIGUSR2</code> in my programs! Why? </A></H4>
+
+The short answer is: because the Linux kernel you're using does not
+support realtime signals.  <P>
+
+LinuxThreads needs two signals for its internal operation.
+One is used to suspend and restart threads blocked on mutex, condition
+or semaphore operations.  The other is used for thread
+cancellation.<P>
+
+On ``old'' kernels (2.0 and early 2.1 kernels), there are only 32
+signals available and the kernel reserves all of them but two:
+<code>SIGUSR1</code> and <code>SIGUSR2</code>.  So, LinuxThreads has
+no choice but use those two signals.<P>
+
+On recent kernels (2.2 and up), more than 32 signals are provided in
+the form of realtime signals. When run on one of those kernels,
+LinuxThreads uses two reserved realtime signals for its internal
+operation, thus leaving <code>SIGUSR1</code> and <code>SIGUSR2</code>
+free for user code.  (This works only with glibc, not with libc 5.) <P>

+<H4><A NAME="H.5">H.5: Is the stack of one thread visible from the

+
+Yes, you can -- if you're very careful.  The stacks are indeed visible
+from all threads in the system.  Some non-POSIX thread libraries seem
+to map the stacks for all threads at the same virtual addresses and
+change the memory mapping when they switch from one thread to
+another.  But this is not the case for LinuxThreads, as it would make
+context switching between threads more expensive, and at any rate
+might not conform to the POSIX standard.<P>
+
+So, you can take the address of an "auto" variable and pass it to
+other threads via shared data structures.  However, you need to make
+absolutely sure that the function doing this will not return as long
+as other threads need to access this address.  It's the usual mistake

+The best solution is to use X libraries that have been compiled with

+At least, that seems to be the case for RedHat 5 and later.<P>
+
+You can try to recompile yourself the X libraries with multithreading

+
+Another, less involving solution is to call X functions only from the

+
+Signal handlers are shared between all threads: when a thread calls
+<CODE>sigaction()</CODE>, it sets how the signal is handled not only
+for itself, but for all other threads in the program as well.<P>
+
+On the other hand, signal masks are per-thread: each thread chooses
+which signals it blocks independently of others.  At thread creation

+
+That's how it should be.  The POSIX standard mandates that all threads
+should terminate when the process (i.e. the collection of all threads
+running the program) receives a signal whose effect is to
+terminate the process (such as <CODE>SIGKILL</CODE> or <CODE>SIGINT</CODE>
+when no handler is installed on that signal).  This behavior makes a
+lot of sense: when you type "ctrl-C" at the keyboard, or when a thread
+crashes on a division by zero or a segmentation fault, you really want
+all threads to stop immediately, not just the one that caused the
+segmentation violation or that got the <CODE>SIGINT</CODE> signal.
+(This assumes default behavior for those signals; see question
+<A HREF="#J.3">J.3</A> if you install handlers for those signals.)<P>

+
+<H4><A NAME="J.3">J.3: I've installed a handler on a signal.  Which
+thread executes the handler when the signal is received?</A></H4>
+
+If the signal is generated by a thread during its execution (e.g. a
+thread executes a division by zero and thus generates a
+<CODE>SIGFPE</CODE> signal), then the handler is executed by that
+thread.  This also applies to signals generated by
+<CODE>raise()</CODE>.<P>
+
+If the signal is sent to a particular thread using
+<CODE>pthread_kill()</CODE>, then that thread executes the handler.<P>
+
+If the signal is sent via <CODE>kill()</CODE> or the tty interface
+(e.g. by pressing ctrl-C), then the POSIX specs say that the handler
+is executed by any thread in the process that does not currently block
+the signal.  In other terms, POSIX considers that the signal is sent
+to the process (the collection of all threads) as a whole, and any
+thread that is not blocking this signal can then handle it.<P>
+
+The latter case is where LinuxThreads departs from the POSIX specs.
+In LinuxThreads, there is no real notion of ``the process as a whole'':
+in the kernel, each thread is really a distinct process with a
+distinct PID, and signals sent to the PID of a thread can only be
+handled by that thread.  As long as no thread is blocking the signal,
+the behavior conforms to the standard: one (unspecified) thread of the
+program handles the signal.  But if the thread to which PID the signal
+is sent blocks the signal, and some other thread does not block the
+signal, then LinuxThreads will simply queue in
+that thread and execute the handler only when that thread unblocks
+the signal, instead of executing the handler immediately in the other
+thread that does not block the signal.<P>
+
+This is to be viewed as a LinuxThreads bug, but I currently don't see
+any way to implement the POSIX behavior without kernel support.<P>
+
+<H4><A NAME="J.3">J.3: How shall I go about mixing signals and threads

+The less you mix them, the better.  Notice that all

+that you should not call them from signal handlers.  This
+recommendation is not to be taken lightly: your program can deadlock
+if you call a <CODE>pthread_*</CODE> function from a signal handler!
+<P>
+
+The only sensible things you can do from a signal handler is set a
+global flag, or call <CODE>sem_post</CODE> on a semaphore, to record
+the delivery of the signal.  The remainder of the program can then
+either poll the global flag, or use <CODE>sem_wait()</CODE> and
+<CODE>sem_trywait()</CODE> on the semaphore.<P>
+
+Another option is to do nothing in the signal handler, and dedicate
+one thread (preferably the initial thread) to wait synchronously for

+
+It's an unfortunate consequence of how LinuxThreads implements

+Since signal handlers are shared with the other threads, this

+
+Though surprising, this behavior actually seems to conform to the

+
+LinuxThreads follows the so-called "one-to-one" model: each thread is
+actually a separate process in the kernel.  The kernel scheduler takes
+care of scheduling the threads, just like it schedules regular
+processes.  The threads are created with the Linux
+<code>clone()</code> system call, which is a generalization of
+<code>fork()</code> allowing the new process to share the memory
+space, file descriptors, and signal handlers of the parent.<P>

+about one thread per processor);
+<LI> minimal overhead on I/O operations;
+<LI> a simple and robust implementation (the kernel scheduler does
+most of the hard work for us).
+</UL>
+The main disadvantage is more expensive context switches on mutex and

+
+<H4><A NAME="K.2">K.2: Have you considered other implementation

+
+There are basically two other models.  The "many-to-one" model

+one process running.  This model is completely out of the question for
+me, since it does not take advantage of multiprocessors, and require
+unholy magic to handle blocking I/O operations properly.  There are
+several user-level thread libraries available for Linux, but I found
+all of them deficient in functionality, performance, and/or robustness.
+<P>
+
+The "many-to-many" model combines both kernel-level and user-level
+scheduling: several kernel-level threads run concurrently, each
+executing a user-level scheduler that selects between user threads.
+Most commercial Unix systems (Solaris, Digital Unix, IRIX) implement
+POSIX threads this way.  This model combines the advantages of both
+the "many-to-one" and the "one-to-one" model, and is attractive
+because it avoids the worst-case behaviors of both models --
+especially on kernels where context switches are expensive, such as
+Digital Unix.  Unfortunately, it is pretty complex to implement, and
+requires kernel support which Linux does not provide.  Linus Torvalds
+and other Linux kernel developers have always been pushing the
+"one-to-one" model in the name of overall simplicity, and are doing a
+pretty good job of making kernel-level context switches between
+threads efficient.  LinuxThreads is just following the general
+direction they set.<P>

+     
+     Everyone is permitted to copy and distribute verbatim copies
+     of this license document, but changing it is not allowed.
+     
+     [This is the first released version of the library GPL.  It is
+      numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+Preamble
+========
+
+   The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+   This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+   When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it in
+new free programs; and that you know you can do these things.
+
+   To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the library, or if you modify it.
+
+   For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+   Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+   Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+   Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+   Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License, which was designed for utility
+programs.  This license, the GNU Library General Public License,
+applies to certain designated libraries.  This license is quite
+different from the ordinary one; be sure to read it in full, and don't
+assume that anything in it is the same as in the ordinary license.
+
+   The reason we have a separate public license for some libraries is
+that they blur the distinction we usually make between modifying or
+adding to a program and simply using it.  Linking a program with a
+library, without changing the library, is in some sense simply using
+the library, and is analogous to running a utility program or
+application program.  However, in a textual and legal sense, the linked
+executable is a combined work, a derivative of the original library,
+and the ordinary General Public License treats it as such.
+
+   Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+   However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended
+to permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to
+achieve this as regards changes in header files, but we have achieved
+it as regards changes in the actual functions of the Library.)  The
+hope is that this will lead to faster development of free libraries.
+
+   The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+   Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+     contains a notice placed by the copyright holder or other
+     authorized party saying it may be distributed under the terms of
+     this Library General Public License (also called "this License").
+     Each licensee is addressed as "you".
+
+     A "library" means a collection of software functions and/or data
+     prepared so as to be conveniently linked with application programs
+     (which use some of those functions and data) to form executables.
+
+     The "Library", below, refers to any such software library or work
+     which has been distributed under these terms.  A "work based on the
+     Library" means either the Library or any derivative work under
+     copyright law: that is to say, a work containing the Library or a
+     portion of it, either verbatim or with modifications and/or
+     translated straightforwardly into another language.  (Hereinafter,
+     translation is included without limitation in the term
+     "modification".)
+
+     "Source code" for a work means the preferred form of the work for
+     making modifications to it.  For a library, complete source code
+     means all the source code for all modules it contains, plus any
+     associated interface definition files, plus the scripts used to
+     control compilation and installation of the library.
+
+     Activities other than copying, distribution and modification are
+     not covered by this License; they are outside its scope.  The act
+     of running a program using the Library is not restricted, and
+     output from such a program is covered only if its contents
+     constitute a work based on the Library (independent of the use of
+     the Library in a tool for writing it).  Whether that is true
+     depends on what the Library does and what the program that uses
+     the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+     complete source code as you receive it, in any medium, provided
+     that you conspicuously and appropriately publish on each copy an
+     appropriate copyright notice and disclaimer of warranty; keep
+     intact all the notices that refer to this License and to the
+     absence of any warranty; and distribute a copy of this License
+     along with the Library.
+
+     You may charge a fee for the physical act of transferring a copy,
+     and you may at your option offer warranty protection in exchange
+     for a fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+     of it, thus forming a work based on the Library, and copy and
+     distribute such modifications or work under the terms of Section 1
+     above, provided that you also meet all of these conditions:
+
+       a. The modified work must itself be a software library.
+
+       b. You must cause the files modified to carry prominent notices
+          stating that you changed the files and the date of any change.
+
+       c. You must cause the whole of the work to be licensed at no
+          charge to all third parties under the terms of this License.
+
+       d. If a facility in the modified Library refers to a function or
+          a table of data to be supplied by an application program that
+          uses the facility, other than as an argument passed when the
+          facility is invoked, then you must make a good faith effort
+          to ensure that, in the event an application does not supply
+          such function or table, the facility still operates, and
+          performs whatever part of its purpose remains meaningful.
+
+          (For example, a function in a library to compute square roots
+          has a purpose that is entirely well-defined independent of the
+          application.  Therefore, Subsection 2d requires that any
+          application-supplied function or table used by this function
+          must be optional: if the application does not supply it, the
+          square root function must still compute square roots.)
+
+     These requirements apply to the modified work as a whole.  If
+     identifiable sections of that work are not derived from the
+     Library, and can be reasonably considered independent and separate
+     works in themselves, then this License, and its terms, do not
+     apply to those sections when you distribute them as separate
+     works.  But when you distribute the same sections as part of a
+     whole which is a work based on the Library, the distribution of
+     the whole must be on the terms of this License, whose permissions
+     for other licensees extend to the entire whole, and thus to each
+     and every part regardless of who wrote it.
+
+     Thus, it is not the intent of this section to claim rights or
+     contest your rights to work written entirely by you; rather, the
+     intent is to exercise the right to control the distribution of
+     derivative or collective works based on the Library.
+
+     In addition, mere aggregation of another work not based on the
+     Library with the Library (or with a work based on the Library) on
+     a volume of a storage or distribution medium does not bring the
+     other work under the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+     License instead of this License to a given copy of the Library.
+     To do this, you must alter all the notices that refer to this
+     License, so that they refer to the ordinary GNU General Public
+     License, version 2, instead of to this License.  (If a newer
+     version than version 2 of the ordinary GNU General Public License
+     has appeared, then you can specify that version instead if you
+     wish.)  Do not make any other change in these notices.
+
+     Once this change is made in a given copy, it is irreversible for
+     that copy, so the ordinary GNU General Public License applies to
+     all subsequent copies and derivative works made from that copy.
+
+     This option is useful when you wish to copy part of the code of
+     the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+     derivative of it, under Section 2) in object code or executable
+     form under the terms of Sections 1 and 2 above provided that you
+     accompany it with the complete corresponding machine-readable
+     source code, which must be distributed under the terms of Sections
+     1 and 2 above on a medium customarily used for software
+     interchange.
+
+     If distribution of object code is made by offering access to copy
+     from a designated place, then offering equivalent access to copy
+     the source code from the same place satisfies the requirement to
+     distribute the source code, even though third parties are not
+     compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+     Library, but is designed to work with the Library by being
+     compiled or linked with it, is called a "work that uses the
+     Library".  Such a work, in isolation, is not a derivative work of
+     the Library, and therefore falls outside the scope of this License.
+
+     However, linking a "work that uses the Library" with the Library
+     creates an executable that is a derivative of the Library (because
+     it contains portions of the Library), rather than a "work that
+     uses the library".  The executable is therefore covered by this
+     License.  Section 6 states terms for distribution of such
+     executables.
+
+     When a "work that uses the Library" uses material from a header
+     file that is part of the Library, the object code for the work may
+     be a derivative work of the Library even though the source code is
+     not.  Whether this is true is especially significant if the work
+     can be linked without the Library, or if the work is itself a
+     library.  The threshold for this to be true is not precisely
+     defined by law.
+
+     If such an object file uses only numerical parameters, data
+     structure layouts and accessors, and small macros and small inline
+     functions (ten lines or less in length), then the use of the object
+     file is unrestricted, regardless of whether it is legally a
+     derivative work.  (Executables containing this object code plus
+     portions of the Library will still fall under Section 6.)
+
+     Otherwise, if the work is a derivative of the Library, you may
+     distribute the object code for the work under the terms of Section
+     6.  Any executables containing that work also fall under Section 6,
+     whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+     link a "work that uses the Library" with the Library to produce a
+     work containing portions of the Library, and distribute that work
+     under terms of your choice, provided that the terms permit
+     modification of the work for the customer's own use and reverse
+     engineering for debugging such modifications.
+
+     You must give prominent notice with each copy of the work that the
+     Library is used in it and that the Library and its use are covered
+     by this License.  You must supply a copy of this License.  If the
+     work during execution displays copyright notices, you must include
+     the copyright notice for the Library among them, as well as a
+     reference directing the user to the copy of this License.  Also,
+     you must do one of these things:
+
+       a. Accompany the work with the complete corresponding
+          machine-readable source code for the Library including
+          whatever changes were used in the work (which must be
+          distributed under Sections 1 and 2 above); and, if the work
+          is an executable linked with the Library, with the complete
+          machine-readable "work that uses the Library", as object code
+          and/or source code, so that the user can modify the Library
+          and then relink to produce a modified executable containing
+          the modified Library.  (It is understood that the user who
+          changes the contents of definitions files in the Library will
+          not necessarily be able to recompile the application to use
+          the modified definitions.)
+
+       b. Accompany the work with a written offer, valid for at least
+          three years, to give the same user the materials specified in
+          Subsection 6a, above, for a charge no more than the cost of
+          performing this distribution.
+
+       c. If distribution of the work is made by offering access to copy
+          from a designated place, offer equivalent access to copy the
+          above specified materials from the same place.
+
+       d. Verify that the user has already received a copy of these
+          materials or that you have already sent this user a copy.
+
+     For an executable, the required form of the "work that uses the
+     Library" must include any data and utility programs needed for
+     reproducing the executable from it.  However, as a special
+     exception, the source code distributed need not include anything
+     that is normally distributed (in either source or binary form)
+     with the major components (compiler, kernel, and so on) of the
+     operating system on which the executable runs, unless that
+     component itself accompanies the executable.
+
+     It may happen that this requirement contradicts the license
+     restrictions of other proprietary libraries that do not normally
+     accompany the operating system.  Such a contradiction means you
+     cannot use both them and the Library together in an executable
+     that you distribute.
+
+  7. You may place library facilities that are a work based on the
+     Library side-by-side in a single library together with other
+     library facilities not covered by this License, and distribute
+     such a combined library, provided that the separate distribution
+     of the work based on the Library and of the other library
+     facilities is otherwise permitted, and provided that you do these
+     two things:
+
+       a. Accompany the combined library with a copy of the same work
+          based on the Library, uncombined with any other library
+          facilities.  This must be distributed under the terms of the
+          Sections above.
+
+       b. Give prominent notice with the combined library of the fact
+          that part of it is a work based on the Library, and explaining
+          where to find the accompanying uncombined form of the same
+          work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute the
+     Library except as expressly provided under this License.  Any
+     attempt otherwise to copy, modify, sublicense, link with, or
+     distribute the Library is void, and will automatically terminate
+     your rights under this License.  However, parties who have
+     received copies, or rights, from you under this License will not
+     have their licenses terminated so long as such parties remain in
+     full compliance.
+
+  9. You are not required to accept this License, since you have not
+     signed it.  However, nothing else grants you permission to modify
+     or distribute the Library or its derivative works.  These actions
+     are prohibited by law if you do not accept this License.
+     Therefore, by modifying or distributing the Library (or any work
+     based on the Library), you indicate your acceptance of this
+     License to do so, and all its terms and conditions for copying,
+     distributing or modifying the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+     Library), the recipient automatically receives a license from the
+     original licensor to copy, distribute, link with or modify the
+     Library subject to these terms and conditions.  You may not impose
+     any further restrictions on the recipients' exercise of the rights
+     granted herein.  You are not responsible for enforcing compliance
+     by third parties to this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+     infringement or for any other reason (not limited to patent
+     issues), conditions are imposed on you (whether by court order,
+     agreement or otherwise) that contradict the conditions of this
+     License, they do not excuse you from the conditions of this
+     License.  If you cannot distribute so as to satisfy simultaneously
+     your obligations under this License and any other pertinent
+     obligations, then as a consequence you may not distribute the
+     Library at all.  For example, if a patent license would not permit
+     royalty-free redistribution of the Library by all those who
+     receive copies directly or indirectly through you, then the only
+     way you could satisfy both it and this License would be to refrain
+     entirely from distribution of the Library.
+
+     If any portion of this section is held invalid or unenforceable
+     under any particular circumstance, the balance of the section is
+     intended to apply, and the section as a whole is intended to apply
+     in other circumstances.
+
+     It is not the purpose of this section to induce you to infringe any
+     patents or other property right claims or to contest validity of
+     any such claims; this section has the sole purpose of protecting
+     the integrity of the free software distribution system which is
+     implemented by public license practices.  Many people have made
+     generous contributions to the wide range of software distributed
+     through that system in reliance on consistent application of that
+     system; it is up to the author/donor to decide if he or she is
+     willing to distribute software through any other system and a
+     licensee cannot impose that choice.
+
+     This section is intended to make thoroughly clear what is believed
+     to be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+     certain countries either by patents or by copyrighted interfaces,
+     the original copyright holder who places the Library under this
+     License may add an explicit geographical distribution limitation
+     excluding those countries, so that distribution is permitted only
+     in or among countries not thus excluded.  In such case, this
+     License incorporates the limitation as if written in the body of
+     this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+     versions of the Library General Public License from time to time.
+     Such new versions will be similar in spirit to the present version,
+     but may differ in detail to address new problems or concerns.
+
+     Each version is given a distinguishing version number.  If the
+     Library specifies a version number of this License which applies
+     to it and "any later version", you have the option of following
+     the terms and conditions either of that version or of any later
+     version published by the Free Software Foundation.  If the Library
+     does not specify a license version number, you may choose any
+     version ever published by the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+     programs whose distribution conditions are incompatible with these,
+     write to the author to ask for permission.  For software which is
+     copyrighted by the Free Software Foundation, write to the Free
+     Software Foundation; we sometimes make exceptions for this.  Our
+     decision will be guided by the two goals of preserving the free
+     status of all derivatives of our free software and of promoting
+     the sharing and reuse of software generally.
+
+                                NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+     WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
+     LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+     HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
+     WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+     NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+     FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE
+     QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU.  SHOULD THE
+     LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+     SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
+     MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
+     LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+     INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+     INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF
+     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
+     OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY
+     OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+                      END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+==============================================
+
+   If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of
+the ordinary General Public License).
+
+   To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should have
+at least the "copyright" line and a pointer to where the full notice is
+found.
+
+     ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.
+     Copyright (C) YEAR  NAME OF AUTHOR
+     
+     This library is free software; you can redistribute it and/or modify it
+     under the terms of the GNU Library General Public License as published
+     by the Free Software Foundation; either version 2 of the License, or (at
+     your option) any later version.
+     
+     This library is distributed in the hope that it will be useful, but
+     WITHOUT ANY WARRANTY; without even the implied warranty of
+     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+     Library General Public License for more details.

+        Linuxthreads - POSIX 1003.1c kernel threads for Linux
+
+      Copyright 1996, 1997 Xavier Leroy (Xavier.Leroy@inria.fr)
+
+
+DESCRIPTION:
+
+This is release 0.7 (late beta) of LinuxThreads, a BiCapitalized
+implementation of the Posix 1003.1c "pthread" interface for Linux.
+
+LinuxThreads provides kernel-level threads: each thread is a separate
+Unix process, sharing its address space with the other threads through
+the new system call clone(). Scheduling between threads is handled by
+the kernel scheduler, just like scheduling between Unix processes.
+
+
+REQUIREMENTS:
+
+- Linux version 2.0 and up (requires the new clone() system call
+  and the new realtime scheduler).
+
+- For Intel platforms: libc 5.2.18 or later is required.
+  5.2.18 or 5.4.12 or later are recommended;
+  5.3.12 and 5.4.7 have problems (see the FAQ.html file for more info).
+
+- Also supports glibc 2 (a.k.a. libc 6), which actually comes with
+  a specially-adapted version of this library.
+
+- Currently supports Intel, Alpha, Sparc, Motorola 68k, ARM and MIPS
+  platforms.
+
+- Multiprocessors are supported.
+
+
+INSTALLATION:
+
+- Edit the Makefile, set the variables in the "Configuration" section.
+
+- Do "make".
+
+- Do "make install".
+
+
+USING LINUXTHREADS:
+
+        gcc -D_REENTRANT ... -lpthread
+
+A complete set of manual pages is included. Also see the subdirectory
+Examples/ for some sample programs.
+
+
+STATUS:
+
+- All functions in the Posix 1003.1c base interface implemented.
+  Also supports priority scheduling.
+
+- For users of libc 5 (H.J.Lu's libc), a number of C library functions
+  are reimplemented or wrapped to make them thread-safe, including:
+  * malloc functions
+  * stdio functions (define _REENTRANT before including <stdio.h>)
+  * per-thread errno variable (define _REENTRANT before including <errno.h>)
+  * directory reading functions (opendir(), etc)
+  * sleep()
+  * gmtime(), localtime()
+
+  New library functions provided:
+  * flockfile(), funlockfile(), ftrylockfile()
+  * reentrant versions of network database functions (gethostbyname_r(), etc)
+    and password functions (getpwnam_r(), etc).
+
+- libc 6 (glibc 2) provides much better thread support than libc 5,
+  and comes with a specially-adapted version of LinuxThreads.
+  For serious multithreaded programming, you should consider switching
+  to glibc 2. It is available from ftp.gnu.org:/pub/gnu and its mirrors.
+
+
+WARNING:
+
+Many existing libraries are not compatible with LinuxThreads,
+either because they are not inherently thread-safe, or because they
+have not been compiled with the -D_REENTRANT.  For more info, see the
+FAQ.html file in this directory.
+
+A prime example of the latter is Xlib. If you link it with
+LinuxThreads, you'll probably get an "unknown 0 error" very
+early. This is just a consequence of the Xlib binaries using the
+global variable "errno" to fetch error codes, while LinuxThreads and
+the C library use the per-thread "errno" location.
+
+See the file README.Xfree3.3 for info on how to compile the Xfree 3.3
+libraries to make them compatible with LinuxThreads.
+
+
+KNOWN BUGS AND LIMITATIONS:
+
+- Threads share pretty much everything they should share according
+  to the standard: memory space, file descriptors, signal handlers,
+  current working directory, etc. One thing that they do not share
+  is their pid's and parent pid's. According to the standard, they
+  should have the same, but that's one thing we cannot achieve
+  in this implementation (until the CLONE_PID flag to clone() becomes
+  usable).
+
+- The current implementation uses the two signals SIGUSR1 and SIGUSR2,
+  so user-level code cannot employ them. Ideally, there should be two
+  signals reserved for this library. One signal is used for restarting
+  threads blocked on mutexes or conditions; the other is for thread
+  cancellation.
+
+  *** This is not anymore true when the application runs on a kernel
+      newer than approximately 2.1.60.
+
+- The stacks for the threads are allocated high in the memory space,
+  below the stack of the initial process, and spaced 2M apart.
+  Stacks are allocated with the "grow on demand" flag, so they don't
+  use much virtual space initially (4k, currently), but can grow
+  up to 2M if needed.
+
+  Reserving such a large address space for each thread means that,
+  on a 32-bit architecture, no more than about 1000 threads can
+  coexist (assuming a 2Gb address space for user processes),
+  but this is reasonable, since each thread uses up one entry in the
+  kernel's process table, which is usually limited to 512 processes.
+
+  Another potential problem of the "grow on demand" scheme is that
+  nothing prevents the user from mmap'ing something in the 2M address
+  window reserved for a thread stack, possibly causing later extensions of
+  that stack to fail. Mapping at fixed addresses should be avoided
+  when using this library.
+
+- Signal handling does not fully conform to the Posix standard,
+  due to the fact that threads are here distinct processes that can be
+  sent signals individually, so there's no notion of sending a signal
+  to "the" process (the collection of all threads).
+  More precisely, here is a summary of the standard requirements
+  and how they are met by the implementation:
+
+  1- Synchronous signals (generated by the thread execution, e.g. SIGFPE)
+     are delivered to the thread that raised them.
+     (OK.)
+
+  2- A fatal asynchronous signal terminates all threads in the process.
+     (OK. The thread manager notices when a thread dies on a signal
+      and kills all other threads with the same signal.)
+
+  3- An asynchronous signal will be delivered to one of the threads
+     of the program which does not block the signal (it is unspecified
+     which).
+     (No, the signal is delivered to the thread it's been sent to,
+      based on the pid of the thread. If that thread is currently
+      blocking the signal, the signal remains pending.)
+
+  4- The signal will be delivered to at most one thread.
+     (OK, except for signals generated from the terminal or sent to
+      the process group, which will be delivered to all threads.)
+
+- The current implementation of the MIPS support assumes a MIPS ISA II
+  processor or better.  These processors support atomic operations by
+  ll/sc instructions.  Older R2000/R3000 series processors are not
+  supported yet; support for these will have higher overhead.
+
+- The current implementation of the ARM support assumes that the SWP
+  (atomic swap register with memory) instruction is available.  This is
+  the case for all processors except for the ARM1 and ARM2.  On StrongARM,
+  the SWP instruction does not bypass the cache, so multi-processor support
+  will be more troublesome.

+This file describes how to make a threaded X11R6.
+
+You need the source-code of XFree-3.2. I used the sources of X11R6.1
+(files: xc-1.tar.gz xc-2.tar.gz xc-3.tar.gz) and the patches to
+XFree-3.2 (files: README.X11.patch R6.1pl1-3.2.diff.gz cfont32.tgz).
+
+Untar the xc-?.tar.gz files in a directory called XF3.2 and apply
+the XFree-3.2 patches as described in README.X11.patch or use the
+whole XFree86 source.
+
+Now apply the thread patch with
+
+patch -p0 < XF3.2.xc.diff
+
+Go to the XF3.2/xc directory and make the whole thing:
+nice make World >& world.log &
+tail -f world.log
+
+Wait a few hours or interrupt the process after the shared libs
+are made. The shared libs are:
+
+XF3.2/xc/lib/ICE/libICE.so.6.0*
+XF3.2/xc/lib/PEX5/libPEX5.so.6.0*
+XF3.2/xc/lib/SM/libSM.so.6.0*
+XF3.2/xc/lib/X11/libX11.so.6.1*
+XF3.2/xc/lib/XIE/libXIE.so.6.0*
+XF3.2/xc/lib/XThrStub/libXThrStub.so.6.0*
+XF3.2/xc/lib/Xaw/libXaw.so.6.1*
+XF3.2/xc/lib/Xext/libXext.so.6.1*
+XF3.2/xc/lib/Xi/libXi.so.6.0*
+XF3.2/xc/lib/Xmu/libXmu.so.6.0*
+XF3.2/xc/lib/Xt/libXt.so.6.0*
+XF3.2/xc/lib/Xtst/libXtst.so.6.1*
+
+(The Program dga didn't compile, but I have not check out why.)
+
+Now you can copy the resulting libs   
+
+cp XF3.2/xc/lib/*/*.so.?.? /usr/X11R6/lib/
+
+and create some links
+
+cd /usr/X11R6/lib/
+ln -s libXThrStub.so.6.0 libXThrStub.so.6
+ln -s libXThrStub.so.6 libXThrStub.so
+
+or use make install (not tested, and needs new configuration).
+
+It is possible with the libXThrSub to compile X11 programs without linking
+libpthread to them and not necessary to recompile already installed
+unthreaded X11 programs, because libXThrSub keeps the dynamic linker quit.
+On the other hand you can link libpthread to a X11 program to use threads.
+
+I used linux 2.0.23 and libc 5.4.7 .

+@c %MENU% The standard threads library
+
+@c This chapter needs more work bigtime. -zw
+
+This chapter describes the pthreads (POSIX threads) library.  This
+library provides support functions for multithreaded programs: thread
+primitives, synchronization objects, and so forth.  It also implements
+POSIX 1003.1b semaphores (not to be confused with System V semaphores).
+
+The threads operations (@samp{pthread_*}) do not use @var{errno}.
+Instead they return an error code directly.  The semaphore operations do
+use @var{errno}.
+
+@menu
+* Basic Thread Operations::     Creating, terminating, and waiting for threads.
+* Thread Attributes::           Tuning thread scheduling.
+* Cancellation::                Stopping a thread before it's done.
+* Cleanup Handlers::            Deallocating resources when a thread is
+                                  canceled.
+* Mutexes::                     One way to synchronize threads.
+* Condition Variables::         Another way.
+* POSIX Semaphores::            And a third way.
+* Thread-Specific Data::        Variables with different values in
+                                  different threads.
+* Threads and Signal Handling:: Why you should avoid mixing the two, and
+                                  how to do it if you must.
+* Threads and Fork::            Interactions between threads and the
+                                  @code{fork} function.

+@deftypefun int pthread_create (pthread_t * @var{thread}, pthread_attr_t * @var{attr}, void * (*@var{start_routine})(void *), void * @var{arg})
+@code{pthread_create} creates a new thread of control that executes
+concurrently with the calling thread. The new thread calls the
+function @var{start_routine}, passing it @var{arg} as first argument. The
+new thread terminates either explicitly, by calling @code{pthread_exit},
+or implicitly, by returning from the @var{start_routine} function. The
+latter case is equivalent to calling @code{pthread_exit} with the result
+returned by @var{start_routine} as exit code.
+
+The @var{attr} argument specifies thread attributes to be applied to the
+new thread. @xref{Thread Attributes}, for details. The @var{attr}
+argument can also be @code{NULL}, in which case default attributes are
+used: the created thread is joinable (not detached) and has an ordinary
+(not realtime) scheduling policy.
+
+On success, the identifier of the newly created thread is stored in the
+location pointed by the @var{thread} argument, and a 0 is returned. On
+error, a non-zero error code is returned.
+
+This function may return the following errors:
+@table @code
+@item EAGAIN
+Not enough system resources to create a process for the new thread,
+or more than @code{PTHREAD_THREADS_MAX} threads are already active.

+@comment POSIX
+@deftypefun void pthread_exit (void *@var{retval})
+@code{pthread_exit} terminates the execution of the calling thread.  All
+cleanup handlers (@pxref{Cleanup Handlers}) that have been set for the
+calling thread with @code{pthread_cleanup_push} are executed in reverse
+order (the most recently pushed handler is executed first). Finalization
+functions for thread-specific data are then called for all keys that
+have non-@code{NULL} values associated with them in the calling thread
+(@pxref{Thread-Specific Data}).  Finally, execution of the calling
+thread is stopped.
+
+The @var{retval} argument is the return value of the thread. It can be
+retrieved from another thread using @code{pthread_join}.
+
+The @code{pthread_exit} function never returns.
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_cancel (pthread_t @var{thread})
+
+@code{pthread_cancel} sends a cancellation request to the thread denoted
+by the @var{thread} argument.  If there is no such thread,
+@code{pthread_cancel} fails and returns @code{ESRCH}.  Otherwise it
+returns 0. @xref{Cancellation}, for details.
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_join (pthread_t @var{th}, void **thread_@var{return})
+@code{pthread_join} suspends the execution of the calling thread until
+the thread identified by @var{th} terminates, either by calling
+@code{pthread_exit} or by being canceled.
+
+If @var{thread_return} is not @code{NULL}, the return value of @var{th}
+is stored in the location pointed to by @var{thread_return}.  The return
+value of @var{th} is either the argument it gave to @code{pthread_exit},
+or @code{PTHREAD_CANCELED} if @var{th} was canceled.
+
+The joined thread @code{th} must be in the joinable state: it must not
+have been detached using @code{pthread_detach} or the
+@code{PTHREAD_CREATE_DETACHED} attribute to @code{pthread_create}.
+
+When a joinable thread terminates, its memory resources (thread
+descriptor and stack) are not deallocated until another thread performs
+@code{pthread_join} on it. Therefore, @code{pthread_join} must be called
+once for each joinable thread created to avoid memory leaks.
+
+At most one thread can wait for the termination of a given
+thread. Calling @code{pthread_join} on a thread @var{th} on which
+another thread is already waiting for termination returns an error.
+
+@code{pthread_join} is a cancellation point. If a thread is canceled
+while suspended in @code{pthread_join}, the thread execution resumes
+immediately and the cancellation is executed without waiting for the
+@var{th} thread to terminate. If cancellation occurs during
+@code{pthread_join}, the @var{th} thread remains not joined.
+
+On success, the return value of @var{th} is stored in the location
+pointed to by @var{thread_return}, and 0 is returned. On error, one of
+the following values is returned:
+@table @code
+@item ESRCH
+No thread could be found corresponding to that specified by @var{th}.
+@item EINVAL
+The @var{th} thread has been detached, or another thread is already
+waiting on termination of @var{th}.
+@item EDEADLK
+The @var{th} argument refers to the calling thread.

+@section Thread Attributes
+
+@comment pthread.h
+@comment POSIX
+
+Threads have a number of attributes that may be set at creation time.
+This is done by filling a thread attribute object @var{attr} of type
+@code{pthread_attr_t}, then passing it as second argument to
+@code{pthread_create}. Passing @code{NULL} is equivalent to passing a
+thread attribute object with all attributes set to their default values.
+
+Attribute objects are consulted only when creating a new thread.  The
+same attribute object can be used for creating several threads.
+Modifying an attribute object after a call to @code{pthread_create} does
+not change the attributes of the thread previously created.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_attr_init (pthread_attr_t *@var{attr})
+@code{pthread_attr_init} initializes the thread attribute object
+@var{attr} and fills it with default values for the attributes. (The
+default values are listed below for each attribute.)
+
+Each attribute @var{attrname} (see below for a list of all attributes)
+can be individually set using the function
+@code{pthread_attr_set@var{attrname}} and retrieved using the function
+@code{pthread_attr_get@var{attrname}}.
+@end deftypefun

+@deftypefun int pthread_attr_destroy (pthread_attr_t *@var{attr})
+@code{pthread_attr_destroy} destroys the attribute object pointed to by

+left in an undefined state, and you must not use it again in a call to
+any pthreads function until it has been reinitialized.

+
+The following thread attributes are supported:
+@table @samp
+@item detachstate
+Choose whether the thread is created in the joinable state (value
+@code{PTHREAD_CREATE_JOINABLE}) or in the detached state
+(@code{PTHREAD_CREATE_DETACHED}).  The default is
+@code{PTHREAD_CREATE_JOINABLE}.
+
+In the joinable state, another thread can synchronize on the thread
+termination and recover its termination code using @code{pthread_join},
+but some of the thread resources are kept allocated after the thread
+terminates, and reclaimed only when another thread performs
+@code{pthread_join} on that thread.
+
+In the detached state, the thread resources are immediately freed when
+it terminates, but @code{pthread_join} cannot be used to synchronize on
+the thread termination.
+
+A thread created in the joinable state can later be put in the detached
+thread using @code{pthread_detach}.
+
+@item schedpolicy
+Select the scheduling policy for the thread: one of @code{SCHED_OTHER}
+(regular, non-realtime scheduling), @code{SCHED_RR} (realtime,
+round-robin) or @code{SCHED_FIFO} (realtime, first-in first-out).
+The default is @code{SCHED_OTHER}.
+@c Not doc'd in our manual: FIXME.
+@c See @code{sched_setpolicy} for more information on scheduling policies.
+
+The realtime scheduling policies @code{SCHED_RR} and @code{SCHED_FIFO}
+are available only to processes with superuser privileges.
+@code{pthread_attr_setschedparam} will fail and return @code{ENOTSUP} if
+you try to set a realtime policy when you are unprivileged.
+
+The scheduling policy of a thread can be changed after creation with
+@code{pthread_setschedparam}.
+
+@item schedparam
+Change the scheduling parameter (the scheduling priority)
+for the thread.  The default is 0.
+
+This attribute is not significant if the scheduling policy is
+@code{SCHED_OTHER}; it only matters for the realtime policies
+@code{SCHED_RR} and @code{SCHED_FIFO}.
+
+The scheduling priority of a thread can be changed after creation with
+@code{pthread_setschedparam}.
+
+@item inheritsched
+Choose whether the scheduling policy and scheduling parameter for the
+newly created thread are determined by the values of the
+@var{schedpolicy} and @var{schedparam} attributes (value
+@code{PTHREAD_EXPLICIT_SCHED}) or are inherited from the parent thread
+(value @code{PTHREAD_INHERIT_SCHED}).  The default is
+@code{PTHREAD_EXPLICIT_SCHED}.
+
+@item scope
+Choose the scheduling contention scope for the created thread.  The
+default is @code{PTHREAD_SCOPE_SYSTEM}, meaning that the threads contend
+for CPU time with all processes running on the machine. In particular,
+thread priorities are interpreted relative to the priorities of all
+other processes on the machine. The other possibility,
+@code{PTHREAD_SCOPE_PROCESS}, means that scheduling contention occurs
+only between the threads of the running process: thread priorities are
+interpreted relative to the priorities of the other threads of the
+process, regardless of the priorities of other processes.
+
+@code{PTHREAD_SCOPE_PROCESS} is not supported in LinuxThreads.  If you
+try to set the scope to this value, @code{pthread_attr_setscope} will
+fail and return @code{ENOTSUP}.
+
+@item stackaddr
+Provide an address for an application managed stack.  The size of the
+stack must be at least @code{PTHREAD_STACK_MIN}.
+
+@item stacksize
+Change the size of the stack created for the thread.  The value defines
+the minimum stack size, in bytes.
+
+If the value exceeds the system's maximum stack size, or is smaller
+than @code{PTHREAD_STACK_MIN}, @code{pthread_attr_setstacksize} will
+fail and return @code{EINVAL}.
+
+@item stack
+Provide both the address and size of an application managed stack to
+use for the new thread.  The base of the memory area is @var{stackaddr}
+with the size of the memory area, @var{stacksize}, measured in bytes.
+
+If the value of @var{stacksize} is less than @code{PTHREAD_STACK_MIN},
+or greater than the system's maximum stack size, or if the value of
+@var{stackaddr} lacks the proper alignment, @code{pthread_attr_setstack}
+will fail and return @code{EINVAL}.
+
+@item guardsize
+Change the minimum size in bytes of the guard area for the thread's
+stack.  The default size is a single page.  If this value is set, it
+will be rounded up to the nearest page size.  If the value is set to 0,
+a guard area will not be created for this thread.  The space allocated
+for the guard area is used to catch stack overflow.  Therefore, when
+allocating large structures on the stack, a larger guard area may be
+required to catch a stack overflow.
+
+If the caller is managing their own stacks (if the @code{stackaddr}
+attribute has been set), then the @code{guardsize} attribute is ignored.
+
+If the value exceeds the @code{stacksize}, @code{pthread_atrr_setguardsize}
+will fail and return @code{EINVAL}.
+@end table
+
+@node Cancellation
+@section Cancellation
+
+Cancellation is the mechanism by which a thread can terminate the
+execution of another thread. More precisely, a thread can send a
+cancellation request to another thread. Depending on its settings, the
+target thread can then either ignore the request, honor it immediately,
+or defer it till it reaches a cancellation point.  When threads are
+first created by @code{pthread_create}, they always defer cancellation
+requests.
+
+When a thread eventually honors a cancellation request, it behaves as if
+@code{pthread_exit(PTHREAD_CANCELED)} was called.  All cleanup handlers
+are executed in reverse order, finalization functions for
+thread-specific data are called, and finally the thread stops executing.
+If the canceled thread was joinable, the return value
+@code{PTHREAD_CANCELED} is provided to whichever thread calls
+@var{pthread_join} on it. See @code{pthread_exit} for more information.
+
+Cancellation points are the points where the thread checks for pending
+cancellation requests and performs them.  The POSIX threads functions
+@code{pthread_join}, @code{pthread_cond_wait},
+@code{pthread_cond_timedwait}, @code{pthread_testcancel},
+@code{sem_wait}, and @code{sigwait} are cancellation points.  In
+addition, these system calls are cancellation points:
+
+@multitable @columnfractions .33 .33 .33
+@item @t{accept}	@tab @t{open}		@tab @t{sendmsg}
+@item @t{close}		@tab @t{pause}		@tab @t{sendto}

+@item @t{msync}		@tab @t{send}		@tab @t{write}
+@item @t{nanosleep}
+@end multitable
+
+@noindent
+All library functions that call these functions (such as
+@code{printf}) are also cancellation points.

+@deftypefun int pthread_setcancelstate (int @var{state}, int *@var{oldstate})

+requests are ignored).
+

+as soon as the cancellation request is received, or
+@code{PTHREAD_CANCEL_DEFERRED} to keep the cancellation request pending
+until the next cancellation point. If @var{oldtype} is not @code{NULL},

+@node Cleanup Handlers
+@section Cleanup Handlers
+
+Cleanup handlers are functions that get called when a thread terminates,
+either by calling @code{pthread_exit} or because of
+cancellation. Cleanup handlers are installed and removed following a
+stack-like discipline.
+
+The purpose of cleanup handlers is to free the resources that a thread
+may hold at the time it terminates. In particular, if a thread exits or
+is canceled while it owns a locked mutex, the mutex will remain locked
+forever and prevent other threads from executing normally. The best way
+to avoid this is, just before locking the mutex, to install a cleanup
+handler whose effect is to unlock the mutex. Cleanup handlers can be
+used similarly to free blocks allocated with @code{malloc} or close file
+descriptors on thread termination.
+
+Here is how to lock a mutex @var{mut} in such a way that it will be
+unlocked if the thread is canceled while @var{mut} is locked:
+
+@smallexample

+@node Mutexes
+@section Mutexes
+
+A mutex is a MUTual EXclusion device, and is useful for protecting
+shared data structures from concurrent modifications, and implementing
+critical sections and monitors.
+
+A mutex has two possible states: unlocked (not owned by any thread),
+and locked (owned by one thread). A mutex can never be owned by two
+different threads simultaneously. A thread attempting to lock a mutex
+that is already locked by another thread is suspended until the owning
+thread unlocks the mutex first.
+
+None of the mutex functions is a cancellation point, not even
+@code{pthread_mutex_lock}, in spite of the fact that it can suspend a
+thread for arbitrary durations. This way, the status of mutexes at
+cancellation points is predictable, allowing cancellation handlers to
+unlock precisely those mutexes that need to be unlocked before the
+thread stops executing. Consequently, threads using deferred
+cancellation should never hold a mutex for extended periods of time.
+
+It is not safe to call mutex functions from a signal handler.  In
+particular, calling @code{pthread_mutex_lock} or
+@code{pthread_mutex_unlock} from a signal handler may deadlock the
+calling thread.

+@node Thread-Specific Data
+@section Thread-Specific Data
+
+Programs often need global or static variables that have different
+values in different threads. Since threads share one memory space, this
+cannot be achieved with regular variables. Thread-specific data is the
+POSIX threads answer to this need.
+
+Each thread possesses a private memory block, the thread-specific data
+area, or TSD area for short. This area is indexed by TSD keys. The TSD
+area associates values of type @code{void *} to TSD keys. TSD keys are
+common to all threads, but the value associated with a given TSD key can
+be different in each thread.
+
+For concreteness, the TSD areas can be viewed as arrays of @code{void *}
+pointers, TSD keys as integer indices into these arrays, and the value
+of a TSD key as the value of the corresponding array element in the
+calling thread.
+
+When a thread is created, its TSD area initially associates @code{NULL}
+with all keys.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_key_create (pthread_key_t *@var{key}, void (*destr_function) (void *))
+@code{pthread_key_create} allocates a new TSD key. The key is stored in
+the location pointed to by @var{key}. There is a limit of
+@code{PTHREAD_KEYS_MAX} on the number of keys allocated at a given
+time. The value initially associated with the returned key is
+@code{NULL} in all currently executing threads.
+
+The @var{destr_function} argument, if not @code{NULL}, specifies a
+destructor function associated with the key. When a thread terminates
+via @code{pthread_exit} or by cancellation, @var{destr_function} is
+called on the value associated with the key in that thread. The
+@var{destr_function} is not called if a key is deleted with
+@code{pthread_key_delete} or a value is changed with
+@code{pthread_setspecific}.  The order in which destructor functions are
+called at thread termination time is unspecified.
+
+Before the destructor function is called, the @code{NULL} value is
+associated with the key in the current thread.  A destructor function
+might, however, re-associate non-@code{NULL} values to that key or some
+other key.  To deal with this, if after all the destructors have been
+called for all non-@code{NULL} values, there are still some
+non-@code{NULL} values with associated destructors, then the process is
+repeated.  The LinuxThreads implementation stops the process after
+@code{PTHREAD_DESTRUCTOR_ITERATIONS} iterations, even if some
+non-@code{NULL} values with associated descriptors remain.  Other
+implementations may loop indefinitely.
+
+@code{pthread_key_create} returns 0 unless @code{PTHREAD_KEYS_MAX} keys

+
+@code{sigwait} is a cancellation point.  It always returns 0.
+@end deftypefun
+
+For @code{sigwait} to work reliably, the signals being waited for must be
+blocked in all threads, not only in the calling thread, since
+otherwise the POSIX semantics for signal delivery do not guarantee
+that it's the thread doing the @code{sigwait} that will receive the signal.
+The best way to achieve this is block those signals before any threads
+are created, and never unblock them in the program other than by
+calling @code{sigwait}.
+
+Signal handling in LinuxThreads departs significantly from the POSIX
+standard. According to the standard, ``asynchronous'' (external) signals
+are addressed to the whole process (the collection of all threads),
+which then delivers them to one particular thread. The thread that
+actually receives the signal is any thread that does not currently block
+the signal.
+
+In LinuxThreads, each thread is actually a kernel process with its own
+PID, so external signals are always directed to one particular thread.
+If, for instance, another thread is blocked in @code{sigwait} on that
+signal, it will not be restarted.
+
+The LinuxThreads implementation of @code{sigwait} installs dummy signal
+handlers for the signals in @var{set} for the duration of the
+wait. Since signal handlers are shared between all threads, other
+threads must not attach their own signal handlers to these signals, or
+alternatively they should all block these signals (which is recommended
+anyway).
+
+@node Threads and Fork
+@section Threads and Fork
+
+It's not intuitively obvious what should happen when a multi-threaded POSIX
+process calls @code{fork}. Not only are the semantics tricky, but you may
+need to write code that does the right thing at fork time even if that code
+doesn't use the @code{fork} function. Moreover, you need to be aware of
+interaction between @code{fork} and some library features like
+@code{pthread_once} and stdio streams.
+
+When @code{fork} is called by one of the threads of a process, it creates a new
+process which is copy of the  calling process. Effectively, in addition to
+copying certain system objects, the function takes a snapshot of the memory
+areas of the parent process, and creates identical areas in the child.
+To make matters more complicated, with threads it's possible for two or more
+threads to concurrently call fork to create two or more child processes.
+
+The child process has a copy of the address space of the parent, but it does
+not inherit any of its threads. Execution of the child process is carried out
+by a new thread which returns from @code{fork} function with a return value of
+zero; it is the only thread in the child process.  Because threads are not
+inherited across fork, issues arise. At the time of the call to @code{fork},
+threads in the parent process other than the one calling @code{fork} may have
+been executing critical regions of code.  As a result, the child process may
+get a copy of objects that are not in a well-defined state.  This potential
+problem affects all components of the program.
+
+Any program component which will continue being used in a child process must
+correctly handle its state during @code{fork}. For this purpose, the POSIX
+interface provides the special function @code{pthread_atfork} for installing
+pointers to handler functions which are called from within @code{fork}.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_atfork (void (*@var{prepare})(void), void (*@var{parent})(void), void (*@var{child})(void))
+
+@code{pthread_atfork} registers handler functions to be called just
+before and just after a new process is created with @code{fork}. The
+@var{prepare} handler will be called from the parent process, just
+before the new process is created. The @var{parent} handler will be
+called from the parent process, just before @code{fork} returns. The
+@var{child} handler will be called from the child process, just before
+@code{fork} returns.
+
+@code{pthread_atfork} returns 0 on success and a non-zero error code on
+error.
+
+One or more of the three handlers @var{prepare}, @var{parent} and
+@var{child} can be given as @code{NULL}, meaning that no handler needs
+to be called at the corresponding point.
+
+@code{pthread_atfork} can be called several times to install several
+sets of handlers. At @code{fork} time, the @var{prepare} handlers are
+called in LIFO order (last added with @code{pthread_atfork}, first
+called before @code{fork}), while the @var{parent} and @var{child}
+handlers are called in FIFO order (first added, first called).
+
+If there is insufficient memory available to register the handlers,
+@code{pthread_atfork} fails and returns @code{ENOMEM}.  Otherwise it
+returns 0.
+
+The functions @code{fork} and @code{pthread_atfork} must not be regarded as
+reentrant from the context of the handlers.  That is to say, if a
+@code{pthread_atfork} handler invoked from within @code{fork} calls
+@code{pthread_atfork} or @code{fork}, the behavior is undefined.
+
+Registering a triplet of handlers is an atomic operation with respect to fork.
+If new handlers are registered at about the same time as a fork occurs, either
+all three handlers will be called, or none of them will be called.
+
+The handlers are inherited by the child process, and there is no
+way to remove them, short of using @code{exec} to load a new
+pocess image.
+
+@end deftypefun
+
+To understand the purpose of @code{pthread_atfork}, recall that
+@code{fork} duplicates the whole memory space, including mutexes in
+their current locking state, but only the calling thread: other threads
+are not running in the child process.  The mutexes are not usable after
+the @code{fork} and must be initialized with @code{pthread_mutex_init}
+in the child process.  This is a limitation of the current
+implementation and might or might not be present in future versions.
+
+To avoid this, install handlers with @code{pthread_atfork} as follows: have the
+@var{prepare} handler lock the mutexes (in locking order), and the
+@var{parent} handler unlock the mutexes. The @var{child} handler should reset
+the mutexes using @code{pthread_mutex_init}, as well as any other
+synchronization objects such as condition variables.
+
+Locking the global mutexes before the fork ensures that all other threads are
+locked out of the critical regions of code protected by those mutexes.  Thus
+when @code{fork} takes a snapshot of the parent's address space, that snapshot
+will copy valid, stable data.  Resetting the synchronization objects in the
+child process will ensure they are properly cleansed of any artifacts from the
+threading subsystem of the parent process. For example, a mutex may inherit
+a wait queue of threads waiting for the lock; this wait queue makes no sense
+in the child process. Initializing the mutex takes care of this.
+
+@node Streams and Fork
+@section Streams and Fork
+
+The GNU standard I/O library has an internal mutex which guards the internal
+linked list of all standard C FILE objects. This mutex is properly taken care
+of during @code{fork} so that the child receives an intact copy of the list.
+This allows the @code{fopen} function, and related stream-creating functions,
+to work correctly in the child process, since these functions need to insert
+into the list.
+
+However, the individual stream locks are not completely taken care of.  Thus
+unless the multithreaded application takes special precautions in its use of
+@code{fork}, the child process might not be able to safely use the streams that
+it inherited from the parent.   In general, for any given open stream in the
+parent that is to be used by the child process, the application must ensure
+that that stream is not in use by another thread when @code{fork} is called.
+Otherwise an inconsistent copy of the stream object be produced. An easy way to
+ensure this is to use @code{flockfile} to lock the stream prior to calling
+@code{fork} and then unlock it with @code{funlockfile} inside the parent
+process, provided that the parent's threads properly honor these locks.
+Nothing special needs to be done in the child process, since the library
+internally resets all stream locks.
+
+Note that the stream locks are not shared between the parent and child.
+For example, even if you ensure that, say, the stream @code{stdout} is properly
+treated and can be safely used in the child, the stream locks do not provide
+an exclusion mechanism between the parent and child. If both processes write
+to @code{stdout}, strangely interleaved output may result regardless of
+the explicit use of @code{flockfile} or implicit locks.
+
+Also note that these provisions are a GNU extension; other systems might not
+provide any way for streams to be used in the child of a multithreaded process.
+POSIX requires that such a child process confines itself to calling only
+asynchronous safe functions, which excludes much of the library, including
+standard I/O.

+@code{pthread_kill_other_threads_np} is a non-portable LinuxThreads extension.
+It causes all threads in the program to terminate immediately, except
+the calling thread which proceeds normally. It is intended to be
+called just before a thread calls one of the @code{exec} functions,

+
+Termination of the other threads is not performed through

+.TH PTHREAD_ATFORK 3 LinuxThreads
+
+.SH NAME
+pthread_atfork \- register handlers to be called at fork(2) time
+
+.SH SYNOPSIS
+#include <pthread.h>
+
+int pthread_atfork(void (*prepare)(void), void (*parent)(void), void (*child)(void));
+
+.SH DESCRIPTION
+
+!pthread_atfork! registers handler functions to be called just before
+and just after a new process is created with !fork!(2). The |prepare|
+handler will be called from the parent process, just before the new
+process is created. The |parent| handler will be called from the parent
+process, just before !fork!(2) returns. The |child| handler will be
+called from the child process, just before !fork!(2) returns.
+
+One or several of the three handlers |prepare|, |parent| and |child|
+can be given as !NULL!, meaning that no handler needs to be called at
+the corresponding point.
+
+!pthread_atfork! can be called several times to install several sets
+of handlers. At !fork!(2) time, the |prepare| handlers are called in
+LIFO order (last added with !pthread_atfork!, first called before !fork!),
+while the |parent| and |child| handlers are called in FIFO order
+(first added, first called).
+
+To understand the purpose of !pthread_atfork!, recall that !fork!(2)
+duplicates the whole memory space, including mutexes in their current
+locking state, but only the calling thread: other threads are not
+running in the child process.  The mutexes are not usable after the
+!fork! and must be initialized with |pthread_mutex_init| in the child
+process.  This is a limitation of the current implementation and might
+or might not be present in future versions.
+
+.SH "RETURN VALUE"
+
+!pthread_atfork! returns 0 on success and a non-zero error code on error.
+
+.SH ERRORS
+.TP
+!ENOMEM!
+insufficient memory available to register the handlers.

+
+int pthread_attr_getscope(const pthread_attr_t *attr, int *scope);
+
+.SH DESCRIPTION
+
+Setting attributes for threads is achieved by filling a
+thread attribute object |attr| of type !pthread_attr_t!, then passing it as
+second argument to !pthread_create!(3). Passing !NULL! is equivalent to
+passing a thread attribute object with all attributes set to their
+default values.
+
+!pthread_attr_init! initializes the thread attribute object |attr| and
+fills it with default values for the attributes. (The default values
+are listed below for each attribute.)
+
+Each attribute |attrname| (see below for a list of all attributes) can
+be individually set using the function !pthread_attr_set!|attrname|
+and retrieved using the function !pthread_attr_get!|attrname|.
+
+!pthread_attr_destroy! destroys a thread attribute object, which
+must not be reused until it is reinitialized. !pthread_attr_destroy!
+does nothing in the LinuxThreads implementation. 
+
+Attribute objects are consulted only when creating a new thread. The
+same attribute object can be used for creating several
+threads. Modifying an attribute object after a call to
+!pthread_create! does not change the attributes of the thread
+previously created.
+
+The following thread attributes are supported:
+
+.SS detachstate
+
+Control whether the thread is created in the joinable state (value
+!PTHREAD_CREATE_JOINABLE!) or in the detached state
+(!PTHREAD_CREATE_DETACHED!). 
+
+Default value: !PTHREAD_CREATE_JOINABLE!.
+
+In the joinable state, another thread can synchronize on the thread
+termination and recover its termination code using !pthread_join!(3),
+but some of the thread resources are kept allocated after the thread
+terminates, and reclaimed only when another thread performs
+!pthread_join!(3) on that thread.
+
+In the detached state, the thread resources are immediately freed when
+it terminates, but !pthread_join!(3) cannot be used to synchronize on
+the thread termination.
+
+A thread created in the joinable state can later be put in the
+detached thread using !pthread_detach!(3).
+
+.SS schedpolicy
+
+Select the scheduling policy for the thread: one of
+!SCHED_OTHER! (regular, non-realtime scheduling),
+!SCHED_RR! (realtime, round-robin) or
+!SCHED_FIFO! (realtime, first-in first-out). See
+!sched_setpolicy!(2) for more information on scheduling policies.
+
+Default value: !SCHED_OTHER!.
+
+The realtime scheduling policies !SCHED_RR! and !SCHED_FIFO! are
+available only to processes with superuser privileges.
+
+The scheduling policy of a thread can be changed after creation with
+!pthread_setschedparam!(3).
+
+.SS schedparam
+
+Contain the scheduling parameters (essentially, the scheduling
+priority) for the thread. See !sched_setparam!(2) for more information
+on scheduling parameters. 
+
+Default value: priority is 0.
+
+This attribute is not significant if the scheduling policy is !SCHED_OTHER!;
+it only matters for the realtime policies !SCHED_RR! and !SCHED_FIFO!.
+
+The scheduling priority of a thread can be changed after creation with
+!pthread_setschedparam!(3).
+
+.SS inheritsched
+
+Indicate whether the scheduling policy and scheduling parameters for
+the newly created thread are determined by the values of the
+|schedpolicy| and |schedparam| attributes (value
+!PTHREAD_EXPLICIT_SCHED!) or are inherited from the parent thread
+(value !PTHREAD_INHERIT_SCHED!).
+
+Default value: !PTHREAD_EXPLICIT_SCHED!.
+
+.SS scope
+
+Define the scheduling contention scope for the created thread.  The
+only value supported in the LinuxThreads implementation is
+!PTHREAD_SCOPE_SYSTEM!, meaning that the threads contend for CPU time
+with all processes running on the machine. In particular, thread
+priorities are interpreted relative to the priorities of all other
+processes on the machine. The other value specified by the standard,
+!PTHREAD_SCOPE_PROCESS!, means that scheduling contention occurs only
+between the threads of the running process: thread priorities are
+interpreted relative to the priorities of the other threads of the
+process, regardless of the priorities of other processes.
+!PTHREAD_SCOPE_PROCESS! is not supported in LinuxThreads.
+
+Default value: !PTHREAD_SCOPE_SYSTEM!.
+
+.SH "RETURN VALUE"
+
+All functions return 0 on success and a non-zero error code on error.
+On success, the !pthread_attr_get!|attrname| functions also store the
+current value of the attribute |attrname| in the location pointed to
+by their second argument.
+
+.SH ERRORS
+
+The !pthread_attr_setdetachstate! function returns the following error
+codes on error:
+.RS
+.TP
+!EINVAL!
+the specified |detachstate| is not one of !PTHREAD_CREATE_JOINABLE! or
+!PTHREAD_CREATE_DETACHED!.

+
+int pthread_setcanceltype(int type, int *oldtype);
+

+
+.SH DESCRIPTION
+
+Cancellation is the mechanism by which a thread can terminate the
+execution of another thread. More precisely, a thread can send a
+cancellation request to another thread. Depending on its settings, the
+target thread can then either ignore the request, honor it
+immediately, or defer it till it reaches a cancellation point.
+
+When a thread eventually honors a cancellation request, it performs as
+if !pthread_exit(PTHREAD_CANCELED)! has been called at that point:
+all cleanup handlers are executed in reverse order, finalization
+functions for thread-specific data are called, and finally the thread
+stops executing with the return value !PTHREAD_CANCELED!. See
+!pthread_exit!(3) for more information.
+
+!pthread_cancel! sends a cancellation request to the thread denoted
+by the |thread| argument.
+
+!pthread_setcancelstate! changes the cancellation state for the
+calling thread -- that is, whether cancellation requests are ignored
+or not. The |state| argument is the new cancellation state: either
+!PTHREAD_CANCEL_ENABLE! to enable cancellation, or
+!PTHREAD_CANCEL_DISABLE! to disable cancellation (cancellation
+requests are ignored). If |oldstate| is not !NULL!, the previous
+cancellation state is stored in the location pointed to by |oldstate|,
+and can thus be restored later by another call to
+!pthread_setcancelstate!.
+
+!pthread_setcanceltype! changes the type of responses to cancellation
+requests for the calling thread: asynchronous (immediate) or deferred.
+The |type| argument is the new cancellation type: either
+!PTHREAD_CANCEL_ASYNCHRONOUS! to cancel the calling thread as soon as
+the cancellation request is received, or !PTHREAD_CANCEL_DEFERRED! to
+keep the cancellation request pending until the next cancellation
+point. If |oldtype| is not !NULL!, the previous
+cancellation state is stored in the location pointed to by |oldtype|,
+and can thus be restored later by another call to
+!pthread_setcanceltype!.
+
+Threads are always created by !pthread_create!(3) with cancellation
+enabled and deferred. That is, the initial cancellation state is
+!PTHREAD_CANCEL_ENABLE! and the initial type is
+!PTHREAD_CANCEL_DEFERRED!.
+
+Cancellation points are those points in the program execution where a
+test for pending cancellation requests is performed and cancellation
+is executed if positive. The following POSIX threads functions
+are cancellation points:
+
+!pthread_join!(3)
+.br
+!pthread_cond_wait!(3)
+.br
+!pthread_cond_timedwait!(3)
+.br
+!pthread_testcancel!(3)
+.br
+!sem_wait!(3)
+.br
+!sigwait!(3)
+
+All other POSIX threads functions are guaranteed not to be
+cancellation points. That is, they never perform cancellation in
+deferred cancellation mode.
+
+!pthread_testcancel! does nothing except testing for pending
+cancellation and executing it. Its purpose is to introduce explicit
+checks for cancellation in long sequences of code that do not call
+cancellation point functions otherwise.

+integrated enough with the C library to implement this, and thus none
+of the C library functions is a cancellation point.
+
+For system calls at least, there is a workaround. Cancellation
+requests are transmitted to the target thread by sending it a
+signal. That signal will interrupt all blocking system calls, causing
+them to return immediately with the !EINTR! error. So, checking for
+cancellation during a !read! system call, for instance, can be
+achieved as follows:

+.SH NAME
+pthread_cleanup_push, pthread_cleanup_pop, pthread_cleanup_push_defer_np, pthread_cleanup_pop_restore_np \- install and remove cleanup handlers
+
+.SH SYNOPSIS
+#include <pthread.h>
+
+void pthread_cleanup_push(void (*routine) (void *), void *arg);
+
+void pthread_cleanup_pop(int execute);
+
+void pthread_cleanup_push_defer_np(void (*routine) (void *), void *arg);
+
+void pthread_cleanup_pop_restore_np(int execute);
+
+.SH DESCRIPTION
+
+Cleanup handlers are functions that get called when a thread
+terminates, either by calling !pthread_exit!(3) or because of
+cancellation. Cleanup handlers are installed and removed following a
+stack-like discipline.
+
+The purpose of cleanup handlers is to free the resources that a thread
+may hold at the time it terminates. In particular, if a thread
+exits or is cancelled while it owns a locked mutex, the mutex will
+remain locked forever and prevent other threads from executing
+normally. The best way to avoid this is, just before locking the
+mutex, to install a cleanup handler whose effect is to unlock the
+mutex. Cleanup handlers can be used similarly to free blocks allocated
+with !malloc!(3) or close file descriptors on thread termination.
+
+!pthread_cleanup_push! installs the |routine| function with argument
+|arg| as a cleanup handler. From this point on to the matching
+!pthread_cleanup_pop!, the function |routine| will be called with
+arguments |arg| when the thread terminates, either through !pthread_exit!(3)
+or by cancellation. If several cleanup handlers are active at that
+point, they are called in LIFO order: the most recently installed
+handler is called first.
+
+!pthread_cleanup_pop! removes the most recently installed cleanup
+handler. If the |execute| argument is not 0, it also executes the
+handler, by calling the |routine| function with arguments |arg|. If
+the |execute| argument is 0, the handler is only removed but not
+executed.
+
+Matching pairs of !pthread_cleanup_push! and !pthread_cleanup_pop!
+must occur in the same function, at the same level of block nesting.
+Actually, !pthread_cleanup_push! and !pthread_cleanup_pop! are macros,
+and the expansion of !pthread_cleanup_push! introduces an open brace !{!
+with the matching closing brace !}! being introduced by the expansion
+of the matching !pthread_cleanup_pop!.
+
+!pthread_cleanup_push_defer_np! is a non-portable extension that
+combines !pthread_cleanup_push! and !pthread_setcanceltype!(3).
+It pushes a cleanup handler just as !pthread_cleanup_push! does, but
+also saves the current cancellation type and sets it to deferred
+cancellation. This ensures that the cleanup mechanism is effective
+even if the thread was initially in asynchronous cancellation mode.
+
+!pthread_cleanup_pop_restore_np! pops a cleanup handler introduced by
+!pthread_cleanup_push_defer_np!, and restores the cancellation type to
+its value at the time !pthread_cleanup_push_defer_np! was called.
+
+!pthread_cleanup_push_defer_np! and !pthread_cleanup_pop_restore_np!
+must occur in matching pairs, at the same level of block nesting.

+
+Here is how to lock a mutex |mut| in such a way that it will be

+.RS
+.ft 3
+.nf
+.sp
+pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);

+.ft 3
+.nf
+.sp
+pthread_cleanup_pop(1);
+.ft
+.LP
+.RE
+.fi
+
+Notice that the code above is safe only in deferred cancellation mode
+(see !pthread_setcanceltype!(3)). In asynchronous cancellation mode,
+a cancellation can occur between !pthread_cleanup_push! and
+!pthread_mutex_lock!, or between !pthread_mutex_unlock! and
+!pthread_cleanup_pop!, resulting in both cases in the thread trying to
+unlock a mutex not locked by the current thread. This is the main
+reason why asynchronous cancellation is difficult to use.
+
+If the code above must also work in asynchronous cancellation mode,
+then it must switch to deferred mode for locking and unlocking the
+mutex:
+
+.RS
+.ft 3
+.nf
+.sp
+pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
+pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);

+
+.SH DESCRIPTION
+
+A condition (short for ``condition variable'') is a synchronization
+device that allows threads to suspend execution and relinquish the
+processors until some predicate on shared data is satisfied. The basic
+operations on conditions are: signal the condition (when the
+predicate becomes true), and wait for the condition, suspending the
+thread execution until another thread signals the condition.
+
+A condition variable must always be associated with a mutex, to avoid
+the race condition where a thread prepares to wait on a condition
+variable and another thread signals the condition just before the
+first thread actually waits on it.
+
+!pthread_cond_init! initializes the condition variable |cond|, using the
+condition attributes specified in |cond_attr|, or default attributes
+if |cond_attr| is !NULL!. The LinuxThreads implementation supports no
+attributes for conditions, hence the |cond_attr| parameter is actually
+ignored.
+
+Variables of type !pthread_cond_t! can also be initialized
+statically, using the constant !PTHREAD_COND_INITIALIZER!.
+
+!pthread_cond_signal! restarts one of the threads that are waiting on
+the condition variable |cond|. If no threads are waiting on |cond|,
+nothing happens. If several threads are waiting on |cond|, exactly one
+is restarted, but it is not specified which.
+
+!pthread_cond_broadcast! restarts all the threads that are waiting on
+the condition variable |cond|. Nothing happens if no threads are
+waiting on |cond|.
+
+!pthread_cond_wait! atomically unlocks the |mutex| (as per
+!pthread_unlock_mutex!) and waits for the condition variable |cond| to
+be signaled. The thread execution is suspended and does not consume
+any CPU time until the condition variable is signaled. The |mutex|
+must be locked by the calling thread on entrance to
+!pthread_cond_wait!. Before returning to the calling thread,
+!pthread_cond_wait! re-acquires |mutex| (as per !pthread_lock_mutex!).
+
+Unlocking the mutex and suspending on the condition variable is done
+atomically. Thus, if all threads always acquire the mutex before
+signaling the condition, this guarantees that the condition cannot be
+signaled (and thus ignored) between the time a thread locks the mutex
+and the time it waits on the condition variable.
+
+!pthread_cond_timedwait! atomically unlocks |mutex| and waits on
+|cond|, as !pthread_cond_wait! does, but it also bounds the duration
+of the wait. If |cond| has not been signaled within the amount of time
+specified by |abstime|, the mutex |mutex| is re-acquired and
+!pthread_cond_timedwait! returns the error !ETIMEDOUT!.
+The |abstime| parameter specifies an absolute time, with the same
+origin as !time!(2) and !gettimeofday!(2): an |abstime| of 0
+corresponds to 00:00:00 GMT, January 1, 1970.
+
+!pthread_cond_destroy! destroys a condition variable, freeing the
+resources it might hold. No threads must be waiting on the condition
+variable on entrance to !pthread_cond_destroy!. In the LinuxThreads
+implementation, no resources are associated with condition variables,
+thus !pthread_cond_destroy! actually does nothing except checking that
+the condition has no waiting threads.
+
+.SH CANCELLATION
+
+!pthread_cond_wait! and !pthread_cond_timedwait! are cancellation
+points. If a thread is cancelled while suspended in one of these
+functions, the thread immediately resumes execution, then locks again
+the |mutex| argument to !pthread_cond_wait! and
+!pthread_cond_timedwait!, and finally executes the cancellation.
+Consequently, cleanup handlers are assured that |mutex| is locked when
+they are called.
+
+.SH "ASYNC-SIGNAL SAFETY"
+
+The condition functions are not async-signal safe, and should not be
+called from a signal handler. In particular, calling
+!pthread_cond_signal! or !pthread_cond_broadcast! from a signal
+handler may deadlock the calling thread.
+
+.SH "RETURN VALUE"
+
+All condition variable functions return 0 on success and a non-zero
+error code on error.
+
+.SH ERRORS
+
+!pthread_cond_init!, !pthread_cond_signal!, !pthread_cond_broadcast!,
+and !pthread_cond_wait! never return an error code.
+
+The !pthread_cond_timedwait! function returns the following error codes
+on error:
+.RS
+.TP
+!ETIMEDOUT!
+the condition variable was not signaled until the timeout specified by
+|abstime|
+
+.TP
+!EINTR!
+!pthread_cond_timedwait! was interrupted by a signal
+.RE
+
+The !pthread_cond_destroy! function returns the following error code
+on error:
+.RS

+
+Condition attributes can be specified at condition creation time, by passing a

+
+.SH DESCRIPTION
+!pthread_create! creates a new thread of control that executes
+concurrently with the calling thread. The new thread applies the
+function |start_routine| passing it |arg| as first argument. The new
+thread terminates either explicitly, by calling !pthread_exit!(3),
+or implicitly, by returning from the |start_routine| function. The
+latter case is equivalent to calling !pthread_exit!(3) with the result
+returned by |start_routine| as exit code.
+
+The |attr| argument specifies thread attributes to be applied to the
+new thread. See !pthread_attr_init!(3) for a complete list of thread
+attributes. The |attr| argument can also be !NULL!, in which case
+default attributes are used: the created thread is joinable (not
+detached) and has default (non real-time) scheduling policy.
+
+.SH "RETURN VALUE"
+On success, the identifier of the newly created thread is stored in

+.SH DESCRIPTION
+!pthread_detach! put the thread |th| in the detached state. This

+from synchronizing on the termination of |th| using !pthread_join!.
+
+A thread can be created initially in the detached state, using the

+!pthread_detach! applies to threads created in the joinable state, and
+which need to be put in the detached state later.
+
+After !pthread_detach! completes, subsequent attempts to perform
+!pthread_join! on |th| will fail. If another thread is already joining
+the thread |th| at the time !pthread_detach! is called,
+!pthread_detach! does nothing and leaves |th| in the joinable state.

+
+int pthread_join(pthread_t th, void **thread_return);
+
+.SH DESCRIPTION
+!pthread_join! suspends the execution of the calling thread until the
+thread identified by |th| terminates, either by calling !pthread_exit!(3)
+or by being cancelled.
+
+If |thread_return| is not !NULL!, the return value of |th| is stored

+|th| is either the argument it gave to !pthread_exit!(3), or

+
+The joined thread !th! must be in the joinable state: it must not have
+been detached using !pthread_detach!(3) or the
+!PTHREAD_CREATE_DETACHED! attribute to !pthread_create!(3).
+
+When a joinable thread terminates, its memory resources (thread
+descriptor and stack) are not deallocated until another thread
+performs !pthread_join! on it. Therefore, !pthread_join! must be
+called once for each joinable thread created to avoid memory leaks.
+
+At most one thread can wait for the termination of a given
+thread. Calling !pthread_join! on a thread |th| on which another
+thread is already waiting for termination returns an error.
+
+.SH CANCELLATION
+
+!pthread_join! is a cancellation point. If a thread is canceled while
+suspended in !pthread_join!, the thread execution resumes immediately
+and the cancellation is executed without waiting for the |th| thread
+to terminate. If cancellation occurs during !pthread_join!, the |th|
+thread remains not joined.
+

+.TH PTHREAD_SPECIFIC 3 LinuxThreads
+
+.SH NAME
+pthread_key_create, pthread_key_delete, pthread_setspecific, pthread_getspecific \- management of thread-specific data
+
+.SH SYNOPSIS
+#include <pthread.h>
+
+int pthread_key_create(pthread_key_t *key, void (*destr_function) (void *));
+
+int pthread_key_delete(pthread_key_t key);
+
+int pthread_setspecific(pthread_key_t key, const void *pointer);
+
+void * pthread_getspecific(pthread_key_t key);
+
+.SH DESCRIPTION
+
+Programs often need global or static variables that have different
+values in different threads. Since threads share one memory space,
+this cannot be achieved with regular variables. Thread-specific data
+is the POSIX threads answer to this need.
+
+Each thread possesses a private memory block, the thread-specific data
+area, or TSD area for short. This area is indexed by TSD keys. The TSD
+area associates values of type !void *! to TSD keys. TSD keys are
+common to all threads, but the value associated with a given TSD key
+can be different in each thread.
+
+For concreteness, the TSD areas can be viewed as arrays of !void *!
+pointers, TSD keys as integer indices into these arrays, and the value
+of a TSD key as the value of the corresponding array element in the
+calling thread.
+
+When a thread is created, its TSD area initially associates !NULL!
+with all keys.
+
+!pthread_key_create! allocates a new TSD key. The key is stored in the
+location pointed to by |key|. There is a limit of !PTHREAD_KEYS_MAX!
+on the number of keys allocated at a given time. The value initially
+associated with the returned key is !NULL! in all currently executing
+threads.
+
+The |destr_function| argument, if not !NULL!, specifies a destructor
+function associated with the key. When a thread terminates via
+!pthread_exit! or by cancellation, |destr_function| is called with
+arguments the value associated with the key in that thread. The
+|destr_function| is not called if that value is !NULL!. The order in
+which destructor functions are called at thread termination time is
+unspecified.
+
+Before the destructor function is called, the !NULL! value is
+associated with the key in the current thread.  A destructor function
+might, however, re-associate non-!NULL! values to that key or some
+other key.  To deal with this, if after all the destructors have been
+called for all non-!NULL! values, there are still some non-!NULL!
+values with associated destructors, then the process is repeated.  The
+LinuxThreads implementation stops the process after
+!PTHREAD_DESTRUCTOR_ITERATIONS! iterations, even if some non-!NULL!
+values with associated descriptors remain.  Other implementations may
+loop indefinitely.
+
+!pthread_key_delete! deallocates a TSD key. It does not check whether
+non-!NULL! values are associated with that key in the currently
+executing threads, nor call the destructor function associated with
+the key.
+
+!pthread_setspecific! changes the value associated with |key| in the
+calling thread, storing the given |pointer| instead.
+
+!pthread_getspecific! returns the value currently associated with
+|key| in the calling thread.
+
+.SH "RETURN VALUE"
+
+!pthread_key_create!, !pthread_key_delete!, and !pthread_setspecific!
+return 0 on success and a non-zero error code on failure. If
+successful, !pthread_key_create! stores the newly allocated key in the
+location pointed to by its |key| argument.

+success, and !NULL! on error.

+.TH PTHREAD_KILL_OTHER_THREADS_NP 3 LinuxThreads
+
+.SH NAME
+pthread_kill_other_threads_np \- terminate all threads in program except calling thread
+
+.SH SYNOPSIS
+#include <pthread.h>
+
+void pthread_kill_other_threads_np(void);
+
+.SH DESCRIPTION
+!pthread_kill_other_threads_np! is a non-portable LinuxThreads extension.
+It causes all threads in the program to terminate immediately, except
+the calling thread which proceeds normally. It is intended to be
+called just before a thread calls one of the !exec! functions,
+e.g. !execve!(2).
+
+Termination of the other threads is not performed through
+!pthread_cancel!(3) and completely bypasses the cancellation
+mechanism. Hence, the current settings for cancellation state and
+cancellation type are ignored, and the cleanup handlers are not
+executed in the terminated threads.

+
+.SH "SEE ALSO"
+!execve!(2),
+!pthread_setcancelstate!(3),
+!pthread_setcanceltype!(3),
+!pthread_cancel!(3).
+
+.SH BUGS
+
+According to POSIX 1003.1c, a successful !exec*! in one of the threads
+should terminate automatically all other threads in the program.
+This behavior is not yet implemented in LinuxThreads.
+Calling !pthread_kill_other_threads_np! before !exec*! achieves much
+of the same behavior, except that if !exec*! ultimately fails, then
+all other threads are already killed.

+.SH DESCRIPTION
+A mutex is a MUTual EXclusion device, and is useful for protecting
+shared data structures from concurrent modifications, and implementing
+critical sections and monitors.
+
+A mutex has two possible states: unlocked (not owned by any thread),
+and locked (owned by one thread). A mutex can never be owned by two
+different threads simultaneously. A thread attempting to lock a mutex
+that is already locked by another thread is suspended until the owning
+thread unlocks the mutex first.
+
+!pthread_mutex_init! initializes the mutex object pointed to by
+|mutex| according to the mutex attributes specified in |mutexattr|.
+If |mutexattr| is !NULL!, default attributes are used instead.
+
+The LinuxThreads implementation supports only one mutex attributes,
+the |mutex kind|, which is either ``fast'', ``recursive'', or
+``error checking''. The kind of a mutex determines whether
+it can be locked again by a thread that already owns it.
+The default kind is ``fast''. See !pthread_mutexattr_init!(3) for more
+information on mutex attributes.
+
+Variables of type !pthread_mutex_t! can also be initialized
+statically, using the constants !PTHREAD_MUTEX_INITIALIZER! (for fast
+mutexes), !PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP! (for recursive
+mutexes), and !PTHREAD_ERRORCHECK_MUTEX_INITIALIZER_NP! (for error checking
+mutexes).
+
+!pthread_mutex_lock! locks the given mutex. If the mutex is currently
+unlocked, it becomes locked and owned by the calling thread, and
+!pthread_mutex_lock! returns immediately. If the mutex is already
+locked by another thread, !pthread_mutex_lock! suspends the calling
+thread until the mutex is unlocked.
+
+If the mutex is already locked by the calling thread, the behavior of
+!pthread_mutex_lock! depends on the kind of the mutex. If the mutex is
+of the ``fast'' kind, the calling thread is suspended until the mutex
+is unlocked, thus effectively causing the calling thread to
+deadlock. If the mutex is of the ``error checking'' kind,
+!pthread_mutex_lock! returns immediately with the error code !EDEADLK!.
+If the mutex is of the ``recursive'' kind, !pthread_mutex_lock!
+succeeds and returns immediately, recording the number of times the
+calling thread has locked the mutex. An equal number of
+!pthread_mutex_unlock! operations must be performed before the mutex
+returns to the unlocked state.
+
+!pthread_mutex_trylock! behaves identically to !pthread_mutex_lock!,
+except that it does not block the calling thread if the mutex is
+already locked by another thread (or by the calling thread in the case
+of a ``fast'' mutex). Instead, !pthread_mutex_trylock! returns
+immediately with the error code !EBUSY!.
+
+!pthread_mutex_unlock! unlocks the given mutex. The mutex is assumed
+to be locked and owned by the calling thread on entrance to
+!pthread_mutex_unlock!. If the mutex is of the ``fast'' kind,
+!pthread_mutex_unlock! always returns it to the unlocked state. If it
+is of the ``recursive'' kind, it decrements the locking count of the
+mutex (number of !pthread_mutex_lock! operations performed on it by
+the calling thread), and only when this count reaches zero is the
+mutex actually unlocked.
+
+On ``error checking'' mutexes, !pthread_mutex_unlock! actually checks
+at run-time that the mutex is locked on entrance, and that it was
+locked by the same thread that is now calling !pthread_mutex_unlock!.
+If these conditions are not met, an error code is returned and the
+mutex remains unchanged.  ``Fast'' and ``recursive'' mutexes perform
+no such checks, thus allowing a locked mutex to be unlocked by a
+thread other than its owner. This is non-portable behavior and must
+not be relied upon.
+
+!pthread_mutex_destroy! destroys a mutex object, freeing the resources
+it might hold. The mutex must be unlocked on entrance. In the
+LinuxThreads implementation, no resources are associated with mutex
+objects, thus !pthread_mutex_destroy! actually does nothing except
+checking that the mutex is unlocked.
+
+.SH CANCELLATION
+
+None of the mutex functions is a cancellation point, not even
+!pthread_mutex_lock!, in spite of the fact that it can suspend a
+thread for arbitrary durations. This way, the status of mutexes at
+cancellation points is predictable, allowing cancellation handlers to
+unlock precisely those mutexes that need to be unlocked before the
+thread stops executing. Consequently, threads using deferred
+cancellation should never hold a mutex for extended periods of time.
+
+.SH "ASYNC-SIGNAL SAFETY"
+
+The mutex functions are not async-signal safe. What this means is that
+they should not be called from a signal handler. In particular,
+calling !pthread_mutex_lock! or !pthread_mutex_unlock! from a signal
+handler may deadlock the calling thread.
+
+.SH "RETURN VALUE"
+
+!pthread_mutex_init! always returns 0. The other mutex functions
+return 0 on success and a non-zero error code on error.
+
+.SH ERRORS
+
+The !pthread_mutex_lock! function returns the following error code
+on error:
+.RS
+.TP
+!EINVAL!
+the mutex has not been properly initialized.
+
+.TP
+!EDEADLK!
+the mutex is already locked by the calling thread

+
+int pthread_mutexattr_init(pthread_mutexattr_t *attr);
+

+
+.SH DESCRIPTION
+
+Mutex attributes can be specified at mutex creation time, by passing a
+mutex attribute object as second argument to !pthread_mutex_init!(3).
+Passing !NULL! is equivalent to passing a mutex attribute object with
+all attributes set to their default values.
+
+!pthread_mutexattr_init! initializes the mutex attribute object |attr|
+and fills it with default values for the attributes.
+
+!pthread_mutexattr_destroy! destroys a mutex attribute object, which
+must not be reused until it is reinitialized. !pthread_mutexattr_destroy!
+does nothing in the LinuxThreads implementation. 
+
+LinuxThreads supports only one mutex attribute: the mutex kind, which
+is either !PTHREAD_MUTEX_FAST_NP! for ``fast'' mutexes,
+!PTHREAD_MUTEX_RECURSIVE_NP! for ``recursive'' mutexes,
+or !PTHREAD_MUTEX_ERRORCHECK_NP! for ``error checking'' mutexes.
+As the !NP! suffix indicates, this is a non-portable extension to the
+POSIX standard and should not be employed in portable programs.
+
+The mutex kind determines what happens if a thread attempts to lock a
+mutex it already owns with !pthread_mutex_lock!(3). If the mutex is of
+the ``fast'' kind, !pthread_mutex_lock!(3) simply suspends the calling
+thread forever.  If the mutex is of the ``error checking'' kind,
+!pthread_mutex_lock!(3) returns immediately with the error code
+!EDEADLK!.  If the mutex is of the ``recursive'' kind, the call to
+!pthread_mutex_lock!(3) returns immediately with a success return
+code. The number of times the thread owning the mutex has locked it is
+recorded in the mutex. The owning thread must call
+!pthread_mutex_unlock!(3) the same number of times before the mutex
+returns to the unlocked state.
+
+The default mutex kind is ``fast'', that is, !PTHREAD_MUTEX_FAST_NP!.
+
+!pthread_mutexattr_settype! sets the mutex kind attribute in |attr|
+to the value specified by |kind|.
+
+!pthread_mutexattr_gettype! retrieves the current value of the
+mutex kind attribute in |attr| and stores it in the location pointed
+to by |kind|.
+
+.SH "RETURN VALUE"
+!pthread_mutexattr_init!, !pthread_mutexattr_destroy! and
+!pthread_mutexattr_gettype! always return 0.
+
+!pthread_mutexattr_settype! returns 0 on success and a non-zero

+

+

+
+.SH NOTES
+
+For !sigwait! to work reliably, the signals being waited for must be
+blocked in all threads, not only in the calling thread, since
+otherwise the POSIX semantics for signal delivery do not guarantee
+that it's the thread doing the !sigwait! that will receive the signal.
+The best way to achieve this is block those signals before any threads
+are created, and never unblock them in the program other than by
+calling !sigwait!.
+
+.SH BUGS
+
+Signal handling in LinuxThreads departs significantly from the POSIX
+standard. According to the standard, ``asynchronous'' (external)
+signals are addressed to the whole process (the collection of all
+threads), which then delivers them to one particular thread. The
+thread that actually receives the signal is any thread that does
+not currently block the signal.
+
+In LinuxThreads, each thread is actually a kernel process with its own
+PID, so external signals are always directed to one particular thread.
+If, for instance, another thread is blocked in !sigwait! on that
+signal, it will not be restarted.
+
+The LinuxThreads implementation of !sigwait! installs dummy signal
+handlers for the signals in |set| for the duration of the wait. Since
+signal handlers are shared between all threads, other threads must not
+attach their own signal handlers to these signals, or alternatively
+they should all block these signals (which is recommended anyway --
+see the Notes section).

+
+int sem_init(sem_t *sem, int pshared, unsigned int value);
+
+int sem_wait(sem_t * sem);
+
+int sem_trywait(sem_t * sem);
+
+int sem_post(sem_t * sem);
+
+int sem_getvalue(sem_t * sem, int * sval);
+
+int sem_destroy(sem_t * sem);
+
+.SH DESCRIPTION
+This manual page documents POSIX 1003.1b semaphores, not to be
+confused with SystemV semaphores as described in !ipc!(5), !semctl!(2)
+and !semop!(2).
+
+Semaphores are counters for resources shared between threads. The
+basic operations on semaphores are: increment the counter atomically,
+and wait until the counter is non-null and decrement it atomically.
+
+!sem_init! initializes the semaphore object pointed to by |sem|. The
+count associated with the semaphore is set initially to |value|. The
+|pshared| argument indicates whether the semaphore is local to the
+current process (|pshared| is zero) or is to be shared between several
+processes (|pshared| is not zero). LinuxThreads currently does not
+support process-shared semaphores, thus !sem_init! always returns with
+error !ENOSYS! if |pshared| is not zero.
+
+!sem_wait! suspends the calling thread until the semaphore pointed to
+by |sem| has non-zero count. It then atomically decreases the
+semaphore count.
+
+!sem_trywait! is a non-blocking variant of !sem_wait!. If the
+semaphore pointed to by |sem| has non-zero count, the count is
+atomically decreased and !sem_trywait! immediately returns 0.
+If the semaphore count is zero, !sem_trywait! immediately returns with
+error !EAGAIN!.
+
+!sem_post! atomically increases the count of the semaphore pointed to
+by |sem|. This function never blocks and can safely be used in
+asynchronous signal handlers.
+
+!sem_getvalue! stores in the location pointed to by |sval| the current
+count of the semaphore |sem|.
+
+!sem_destroy! destroys a semaphore object, freeing the resources it
+might hold. No threads should be waiting on the semaphore at the time
+!sem_destroy! is called. In the LinuxThreads implementation, no
+resources are associated with semaphore objects, thus !sem_destroy!
+actually does nothing except checking that no thread is waiting on the
+semaphore.
+
+.SH CANCELLATION
+
+!sem_wait! is a cancellation point.
+
+.SH "ASYNC-SIGNAL SAFETY"
+
+On processors supporting atomic compare-and-swap (Intel 486, Pentium
+and later, Alpha, PowerPC, MIPS II, Motorola 68k), the !sem_post!
+function is async-signal safe and can therefore be
+called from signal handlers. This is the only thread synchronization
+function provided by POSIX threads that is async-signal safe.
+
+On the Intel 386 and the Sparc, the current LinuxThreads
+implementation of !sem_post! is not async-signal safe by lack of the
+required atomic operations.
+
+.SH "RETURN VALUE"
+
+The !sem_wait! and !sem_getvalue! functions always return 0.
+All other semaphore functions return 0 on success and -1 on error, in
+addition to writing an error code in !errno!.
+
+.SH ERRORS
+
+The !sem_init! function sets !errno! to the following codes on error:
+.RS
+.TP
+!EINVAL!
+|value| exceeds the maximal counter value !SEM_VALUE_MAX!
+.TP
+!ENOSYS!
+|pshared| is not zero
