From 348ed5157bb4b6ef0e38f18ab8fd8d9910544e6e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 30 Nov 1998 14:21:53 +0000 Subject: Update. 1998-11-30 Andreas Jaeger * nscd/nscd_getpw_r.c: Include nscd_proto.h for prototypes. * sysdeps/generic/errno-loc.c: Include for prototype, undefine errno to get variable. * sysdeps/unix/sysv/linux/i386/setfsuid.c: Include instead of for prototype. * sysdeps/unix/sysv/linux/i386/setfsgid.c: Likewise. 1998-11-30 Ulrich Drepper * misc/err.h: Correct comments and use protected attribute keywords. Reported by Joseph Myers . 1998-11-29 Roland McGrath * malloc/thread-m.h [_LIBC]: Include , and remove tsd stuff from pthreads/cthreads libc sections. Use __libc_tsd_define for MALLOC key. [_LIBC] (tsd_key_t, tsd_key_create): Define to a zero-size type and a no-op, respectively. [_LIBC] (tsd_setspecific, tsd_getspecific): Use __libc_tsd_get/set. * elf/dl-error.c: Include . Use __libc_tsd_define for DL_ERROR key. (tsd_setspecific, tsd_getspecific): Rewritten using __libc_tsd_get/set. * sysdeps/mach/hurd/bits/libc-tsd.h: New file. * sysdeps/generic/bits/libc-tsd.h: New file. * Makefile (distribute): Add bits/libc-tsd.h. 1998-10-12 Roland McGrath * elf/dl-error.c: Remove kludge to check for ld.so load address. There is no need if weak undefined symbols are not used in ld.so; see linuxthreads/ChangeLog for changes to files linuxthreads/sysdeps/pthread/bits/libc-lock.h and linuxthreads/sysdeps/pthread/bits/libc-tsd.h. 1998-11-30 Andreas Jaeger * sysdeps/i386/bits/string.h (__memset_cc): Fix typo (s->__s). * sysdeps/i386/i486/bits/string.h: Add prototypes for all new inline functions. * sysdeps/i386/bits/string.h: Likewise. 1998-11-30 Andreas Jaeger * sysdeps/unix/sysv/linux/alpha/bits/ipc.h: Remove ipc_kludge. 1998-11-30 Andreas Schwab * db2/progs/db_load/db_load.c (main): Avoid -Wparentheses warning. --- sysdeps/generic/bits/libc-tsd.h | 51 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 sysdeps/generic/bits/libc-tsd.h (limited to 'sysdeps/generic/bits') diff --git a/sysdeps/generic/bits/libc-tsd.h b/sysdeps/generic/bits/libc-tsd.h new file mode 100644 index 0000000000..6048d995c8 --- /dev/null +++ b/sysdeps/generic/bits/libc-tsd.h @@ -0,0 +1,51 @@ +/* libc-internal interface for thread-specific data.
