From a18f587da5a0a91bcd1307ed0f122ca2ce994c15 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sat, 7 Dec 1996 03:30:25 +0000 Subject: update from main archive 961206 Sat Dec 7 03:24:36 1996 Ulrich Drepper * configure.in: Discard error message from test in test for bash-2.0. * io/getpw.c: Don't apply getcwd on user supplied buffer. Instead always use temporary buffer and only copy the result. Patch by HJ Lu. * stdlib/canonicalize.c: Likewise. * libio/fileops.c: Change comments according to libg++2.8b5. * libio/iosetvbuf.c: Follow change in libg++-2.8b5 to clear unbuffered flag. Reported by HJ Lu. * manual/nss.texi: Correct prototypes. * misc/syslog.c: Make reentrant. Catch SIGPIPE signal to prevent crash if syslog daemon is restarted. * stdlib/rand_r.c: New file. Implementation of POSIX.2 function rand_r. * stdlib/Makefile (routines): Add rand_r. * sysdeps/stub/libc-lock.h: Define __libc_lock_trylock and __libc_mutex_lock. * configure.in: Add --disable-sanity-check option. * sysdeps/unix/sysv/linux/configure.in: If linuxthreads or des-crypt are not available and --disbale-sanity-check is not given abort with a message. Thu Dec 5 19:19:53 1996 Richard Henderson * posix/glob.c: Tests against STDC_HEADERS should also test __GNU_LIBRARY__. Thu Dec 5 16:20:55 1996 Ulrich Drepper * misc/err.c (vwarn): Set errno again before using %m format. Thu Dec 5 10:14:05 1996 Andreas Jaeger * grp/grp.h: Add declaration of __getgrent_r. * io/fts.c (fts_build): Remove "register" from variables dirbuf and dp since their address is needed. * sysdeps/posix/getcwd.c (__getcwd): Remove "register" from variable d since d's address is needed. * misc/tst-dirname.c (main): Provide prototype. * misc/ioctltst.c (main): Dito. * Makefile: Add gnu/lib-names.h to install-others before including Makerules. Wed Dec 4 16:00:09 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/sys/socketvar.h: New file. Simply use . * sysdeps/unix/sysv/linux/Dist: Add sys/socketvar.h. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=inet)]: Add sys/socketvar.h to sysdep_headers. since the value might be outside the range of the `long int'. --- manual/nss.texi | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'manual/nss.texi') diff --git a/manual/nss.texi b/manual/nss.texi index 074b85702c..4a81edca13 100644 --- a/manual/nss.texi +++ b/manual/nss.texi @@ -378,9 +378,9 @@ the non-reentrant and reentrant versions of our function above are: @smallexample struct hostent *gethostbyname (const char *name) -struct hostent *gethostbyname_r (const char *name, - struct hostent *result_buf, char *buf, - int buflen, int *h_errnop) +int gethostbyname_r (const char *name, struct hostent *result_buf, + char *buf, size_t buflen, struct hostent **result, + int *h_errnop) @end smallexample @noindent @@ -389,7 +389,7 @@ The actual prototype of the function in the NSS modules in this case is @smallexample enum nss_status _nss_files_gethostbyname_r (const char *name, struct hostent *result_buf, - char *buf, int buflen, + char *buf, size_t buflen, int *h_errnop) @end smallexample @@ -553,7 +553,7 @@ the interface.
