* implement robust mutexesRich Felker2011-03-171-0/+1
| | | | | | some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point.
* remove some old cruft from sys/types.hRich Felker2011-03-141-1/+0
|
* pthread.h needs clockid_tRich Felker2011-03-121-0/+1
| | | | | actually it gets this from time.h if _POSIX_C_SOURCE or any other feature test macros are defined, but it breaks if they're not.
* missing const in some pthread_attr_* prototypesRich Felker2011-03-111-8/+8
|
* fix sem_open and sem_close to obey posix semanticsRich Felker2011-03-101-0/+1
| | | | | | | | | multiple opens of the same named semaphore must return the same pointer, and only the last close can unmap it. thus the ugly global state keeping track of mappings. the maximum number of distinct named semaphores that can be opened is limited sufficiently small that the linear searches take trivial time, especially compared to the syscall overhead of these functions.
* fix typos in dirent.hRich Felker2011-03-081-2/+2
|
* fcntl.h should make availabel the mode constants from sys/stat.hRich Felker2011-03-082-8/+20
| | | | also remove some legacy nonsense that crept in.
* add macros for use with d_type extension field in direntRich Felker2011-03-071-0/+14
|
* add prototypes for pthread_condattr_* and pthread_rwlockattr_*Rich Felker2011-03-071-0/+12
|
* preliminaries to adding POSIX semaphoresRich Felker2011-03-032-1/+8
|
* namespace cleanup in sys/mman.hRich Felker2011-03-031-1/+3
|
* implement futimens and utimensatRich Felker2011-02-271-0/+3
|
* cleanup namespace in sys/time.hRich Felker2011-02-271-4/+5
|
* implement fexecveRich Felker2011-02-271-0/+1
|
* fix missing prototype for strsignalRich Felker2011-02-261-0/+1
|
* apply feature test protection to memccpyRich Felker2011-02-241-1/+4
|
* prototypes for GNU asprintf/vasprintfRich Felker2011-02-201-0/+2
|
* include sys/sysmacros.h from sys/types.h when _GNU_SOURCE is definedRich Felker2011-02-201-0/+1
|
* fix typo in inotify structureRich Felker2011-02-201-1/+1
|
* make real symbols for the legacy (nonstandardized) utmp functionsRich Felker2011-02-201-6/+15
| | | | | | | this is needed in the long term for ABI compatibility anyway, and in the immediate, it helps with building broken programs like GNU screen that try to prototype the functions themselves rather than using the header.
* resolve some header namespace non-issuesRich Felker2011-02-201-2/+0
| | | | | after re-reading 2.2.2 of POSIX 2008, all of these are in the correct reserved namespaces and do not need protection.
* move the GNU siginfo renaming so it doesn't lead to mismatching namesRich Felker2011-02-201-1/+4
|
* make sys/param.h not depend on PATH_MAX and NAME_MAXRich Felker2011-02-201-2/+2
| | | | | | | | | | | this is a nonstandard header used only by backwards programs, but for some reason it's extremely popular. the recent namespace cleanup fixes broke it, because PATH_MAX and NAME_MAX will not be defined unless an approriate feature test macro has been defined. moreover, it's too late to just #define _GNU_SOURCE in param.h, since limits.h may have already been included. let's just hard-code standard values and be done with it.
* fix typo in wordexp.h (note that the function is still unimplemented)Rich Felker2011-02-191-1/+1
|
* add syscall wrappers for inotifyRich Felker2011-02-191-0/+55
|
* prototype wait3 and wait4Rich Felker2011-02-192-3/+6
|
* prototypes for brk and sbrkRich Felker2011-02-191-0/+2

* support the ugly and deprecated ucontext and sigcontext header stuff...Rich Felker2011-02-181-20/+3
| | | | | | | | | | | | | | only the structures, not the functions from ucontext.h, are supported at this point. the main goal of this commit is to make modern gcc with dwarf2 unwinding build without errors. honestly, it probably doesn't matter how we define these as long as they have members with the right names to prevent errors while compiling libgcc. the only time they will be used is for propagating exceptions across signal-handler boundaries, which invokes undefined behavior anyway. but as-is, they're probably correct and may be useful to various low-level applications dealing with virtualization, jit code generation, and so on...
* add pthread_atfork interfaceRich Felker2011-02-181-0/+2
| | | | | | | | | note that this presently does not handle consistency of the libc's own global state during forking. as per POSIX 2008, if the parent process was threaded, the child process may only call async-signal-safe functions until one of the exec-family functions is called, so the current behavior is believed to be conformant even if non-ideal. it may be improved at some later time.
* add portable lchown (trivial to support and a few ancient things want it..)Rich Felker2011-02-171-0/+3
|
* reorganize pthread data structures and move the definitions to alltypes.hRich Felker2011-02-172-45/+26
| | | | | | | | this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.
* ucontext is no longer in the standard, so use gnu-friendly struct nameRich Felker2011-02-161-2/+2
| | | | | note that this header is still bogus and needs a lot of work and factoring into arch-dependent parts...
* some gnu software wrongly uses "struct siginfo" instead of siginfo_t...Rich Felker2011-02-161-0/+1
|
