From c0a0f9a32c8baa6ab93d00eb42d92c02e9e146d7 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 24 May 2002 08:49:00 +0000 Subject: Update. 2002-05-21 Isamu Hasegawa * posix/regex.c: Define `inline' as a macro into nothing for the compilers which lack the keyword. * posix/regex.h: (RE_SYNTAX_GNU_AWK): Remove RE_CONTEXT_INVALID_OPS for the compatibility of gawk. * posix/regcomp.c: Add fake implementation of isblank() for the environments which lack the function. Don't use free_charset() in case of non-i18n envs. (build_range_exp): Don't use i18n related code in case of non-i18n envs. (build_collating_symbol): Likewise. (build_equiv_class): Likewise. (build_charclass): Likewise. (re_compile_fastmap_iter): Likewise. (parse_bracket_exp): Likewise. (build_word_op): Likewise. (regfree): Don't use free_charset() in case of non-i18n envs. * posix/regex_internal.h: Remove COMPLEX_BRACKET from re_token_type_t in case of non-i18n envs. Don't define re_charset_t in case of non-i18n envs. Change the type of wcs of re_string_t from wchar_t to wint_t, since we store also WEOF. * posix/regex_internal.c: (re_string_realloc_buffers): Change the type of wcs of re_string_t from wchar_t to wint_t. (re_string_reconstruct): Likewise. (create_ci_newstate): Don't use i18n related code in case of non-i18n envs. (create_cd_newstate): Likewise. 2002-05-24 Ulrich Drepper * iconv/loop.c: Fix typo. 2002-05-23 Jakub Jelinek * inet/ether_line.c (ether_line): Fix a typo causing only lower 4 bits of each ethernet address byte being assigned. Don't modify what line points to. * inet/tst-ether_aton.c (main): Add ether_line tests. 2002-05-23 Marcus Brinkmann * manual/filesys.texi: Don't make readlink example leak memory when readlink fails. --- manual/filesys.texi | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) (limited to 'manual/filesys.texi') diff --git a/manual/filesys.texi b/manual/filesys.texi index e715ec7ad1..a74f32d9fe 100644 --- a/manual/filesys.texi +++ b/manual/filesys.texi @@ -1141,16 +1141,19 @@ char * readlink_malloc (const char *filename) @{ int size = 100; + char *buffer = NULL; while (1) @{ - char *buffer = (char *) xmalloc (size); + buffer = (char *) xrealloc (buffer, size); int nchars = readlink (filename, buffer, size); if (nchars < 0) - return NULL; + @{ + free (buffer); + return NULL; + @} if (nchars < size) return buffer; - free (buffer); size *= 2; @} @} -- cgit v1.2.3
