From 51702635af8445431054291c86aaace7c30b0970 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 7 May 1997 15:31:21 +0000 Subject: Update. * locale/categories.def: Change type of _NL_CTYPE_CLASS_NAMES and _NL_CTYPE_MAP_NAMES field to stringlist. Change name of _NL_CTYPE_CODESET_NAME to "charmap". * locale/localeinfo.h (enum value_type): Add stringlist. * locale/programs/locale.c (show_info): Handle stringlist. * locale/programs/charmap.c (charmap_read): If charmap file is not using the given name try to find it by looking through all available charmap files and compare the code set name. * locale/programs/locale.c (write_charmaps): Also print names of charset in fields in the files. * elf/ldd.bash.in: Correct translatable strings. * posix/TESTS: Add some more tests for character class matching. * posix/regex.c: Merge with GNU awk version. (regex_compile): Use ISO C/amend 1 functions for character class handling. * posix/regex.h: Merge with GNU awk version. * posix/getopt.c: Declare as master copies. * posix/getopt1.c: Likewise. * posix/getopt.h: Likewise. * sysdeps/unix/sysv/linux/sys/mount.h: Add definitions for option value to mount functions. Patch by a sun . * stdio-common/bug4.c (main): Use /tmp/bug4.test for concurrency with other tests. * sunrpc/svc_run.c (svc_exit): New, defined. (svc_run): Test for svc_stop variable. * sysdeps/m68k/s_cexp.c: Rewritten. * sysdeps/m68k/s_cexpf.c: Likewise. * sysdeps/m68k/s_cexpl.c: Likewise. --- nis/nis_ismember.c | 142 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 142 insertions(+) create mode 100644 nis/nis_ismember.c (limited to 'nis/nis_ismember.c') diff --git a/nis/nis_ismember.c b/nis/nis_ismember.c new file mode 100644 index 0000000000..f0d087ca51 --- /dev/null +++ b/nis/nis_ismember.c @@ -0,0 +1,142 @@ +/* Copyright (c) 1997 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Thorsten Kukuk , 1997. + + 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.
