From 59dd864187ee61b6f0bfd7abc85e2fea4b479cb7 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sun, 26 May 1996 19:19:51 +0000 Subject: Sun May 26 15:15:08 1996 Roland McGrath * stdlib/ldiv.c: Deansideclized. Sun May 26 19:39:53 1996 Ulrich Drepper * intl/loadmsgcat.c (_nl_load_domain): Test correct variable after malloc. * string/Makefile (tester-ENV): New variable to suppress message translation in test. * string/tester.c: Add tests for strtok_r and strsep. * sysdeps/i386/i486/strcat.S: Correct some more 8bit operation <-> 32 bit operand conflicts. * sysdeps/i386/strsep.S: Wrapper around to produce strsep function. * sysdeps/i386/strtok.S: Optimized implementation of strtok function. * sysdeps/i386/strtok_r.S: Wrapper around to produce strtok_r function. * sysdeps/generic/strtok.c: Moved here from string/strtok.c. Corrected example in comment. * string/Makefile (routines): Add strtok_r. * sysdeps/generic/strtok_r.c: New file. Implement reentrant version of strtok_r. * string/string.h: Add prototype for strtok_r. * wcsmbs/wcstok.c: Handle illegal SAVE_PTR argument the same as in strtok_r. Sun May 26 13:28:23 1996 Roland McGrath * time/tzset.c (__tzset): Ignore leading : in $TZ; always try tzfile first and fall back to 1003.1 syntax only if it fails. * time/Makefile (install-others): Also install posix/ZONE and right/ZONE for each ZONE in $(zonenames). (z.% rule): Generate rules for right/ZONE and posix/ZONE targets too, the difference begin leapseconds vs /dev/null as 3rd dep. For original ZONE targets use $(leapseconds), to be set in Makeconfig. (target-zone-flavor): New variable. (tzcompile): Use it to get the right -d for posix/ and right/ flavors. * Makeconfig (leapseconds): New variable. * mach/Machrules (%.udeps rule): Depend on Machrules. Emit deps for .uh and .__h files. (%.uh, %.__h rules): Don't depend on %.defs; use #include <$*.defs> instead. Sun May 26 01:06:47 1996 Ulrich Drepper * stdlib/Makefile (routines): Add llabs, lldiv. * stdlib/llabs.c: New file. Implementation of return absolute value of long long argument. * stdlib/lldiv.c: New file. Implementation of division with remainder of long long argument. * stdlib/stdlib.h [__USE_GNU] (lldiv_t): New type for lldiv function. Define prototypes for lldiv and llabs functions. * locale/C-collate.c: Initialize _NL_COLLATE_NRULES element. * stdlib/strtod.c: Replace wchar_t with wint_t. The later is really the type for a single wide character. * string/strxfrm.c (print_val): Define separate version for use as wcsxfrm. Here we don't need UTF8 encoding. * wcsmbs/wchar.h: gcc-2.7.2-960517 finally introduces wint_t in . Use this value and only for older gcc version define in place. (uwchar_t): Remove definition. * wcsmbs/wcscmp.c, wcsmbs/wcscoll.c, wcsmbs/wcsncmp.c, wcsmbs/wcsxfrm.c, wcsmbs/wmemcmp.c: : Don't use uwchar_t as unsigned type. wint_t is intended for this. Sat May 25 14:10:19 1996 Roland McGrath * sysdeps/unix/bsd/direntry.h: Use [1] instead of [0] for d_name to quiet -ansi -pedantic. * sysdeps/unix/common/direntry.h: Likewise. * login/Makefile (headers): Add lastlog.h. * login/lastlog.h: New file. * login/Makefile (CFLAGS): Don't append -D_THREAD_SAFE. * login/utmp.h [_REENTRANT || _THREAD_SAFE]: Replace this conditional with #ifdef __USE_REENTRANT. * features.h (__GNU_LIBRARY__): Set to 6. [_GNU_SOURCE] (_POSIX_SOURCE, _POSIX_C_SOURCE, _BSD_SOURCE, _SVID_SOURCE): Make sure they are all defined. * sysdeps/unix/sysv/linux/gnu/types.h: Instead of including , define _LINUX_TYPES_DONT_EXPORT and then include . * resource/sys/resource.h: Remove trailing commas from enums. * sysdeps/generic/netinet/in.h: Remove trailing commas from enums. * sysdeps/unix/sysv/linux/netinet/in.h: Likewise. --- sysdeps/generic/strtok.c | 73 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 sysdeps/generic/strtok.c (limited to 'sysdeps/generic/strtok.c') diff --git a/sysdeps/generic/strtok.c b/sysdeps/generic/strtok.c new file mode 100644 index 0000000000..954471322b --- /dev/null +++ b/sysdeps/generic/strtok.c @@ -0,0 +1,73 @@ +/* Copyright (C) 1991, 1996 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.
