From 39e16978c3b4ac8eaf2201fac56316623910d9da Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 29 Aug 1997 01:19:12 +0000 Subject: Update. 1997-08-29 02:36 Ulrich Drepper * Makefile (version-info.h): Use ISO form for the date. * catgets/catgetsinfo.h: Include . (struct catalog_obj): Add lock field. (__open_catalog): Remove second parameter from prototype. * catgets/catgets.c (catopen): Initialize lock field. (catgets): Don't pass second parameter to __open_catalog. * catgets/gencat.c: Initialize lock field and don't pass second parameter to __open_catalog. * catgets/open_catalog.c (__open_catalog): Decide about use of path by examining path in struct, not based on extra argument. Acquire a the lock before trying to load the catalog and release it before returning. * csu/Makefile (abi-tag.h): Make sure target directory exists. * io/Makefile (headers): Add bits/poll.h. * io/sys/poll.h: Remove definitions of POLL* constants. Include . * sysdeps/generic/bits/poll.h: New file. * sysdeps/unix/sysv/linux/bits/poll.h: New file. * sysdeps/unix/sysv/linux/m68k/bits/poll.h: New file. * sysdeps/unix/sysv/linux/mips/bits/poll.h: New file. * sysdeps/unix/sysv/linux/sparc/bits/poll.h: New file. * libio/fileops.c (_IO_file_read, _IO_file_write): Remove dead code. * malloc/obstack.c: Add casts to keep very verbose compilers on 64bit machine quiet. * nss/Makefile (libnss_db.so): Find libdb.so in db2 directory. 1997-08-28 17:30 Ulrich Drepper * catgets/catgets.c (catopen): Correctly determine length of string in NLSPATH evironment variable. Patch by HJ Lu . 1997-08-27 23:19 Richard Henderson * sysdeps/generic/dl-sysdep.c (DL_FIND_ARG_COMPONENTS): Provide default macro to track down arguments from stack start. (_dl_sysdep_start): Use it. * sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Truncate to simply providing a special DL_FIND_ARG_COMPONENTS and including the next file up the line. * sysdeps/powerpc/e_sqrt.c: Move contents to w_sqrt.c and provide stub. * sysdeps/powerpc/e_sqrtf.c: Likewise. * sysdeps/powerpc/s_copysignf.S: Provide empty file; symbol is with the double precision version. * sysdeps/powerpc/s_fabsf.S: Likewise. * sysdeps/powerpc/s_isnanf.S: Likewise. --- bits/poll.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 bits/poll.h (limited to 'bits/poll.h') diff --git a/bits/poll.h b/bits/poll.h new file mode 100644 index 0000000..55ec70e --- /dev/null +++ b/bits/poll.h @@ -0,0 +1,38 @@ +/* Copyright (C) 1997 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C 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. + + The GNU C 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.
