From c150923988933b5db75a974d4cc08cd7f7aaf3dc Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Tue, 9 Jul 1996 14:49:13 +0000 Subject: Tue Jul 9 09:37:55 1996 Roland McGrath * sysdeps/mach/libc-lock.h: New file. * sysdeps/unix/readdir.c: Do locking. * sysdeps/unix/seekdir.c: Likewise. * sysdeps/unix/rewinddir.c: Likewise. * sysdeps/unix/closedir.c: Likewise. * sysdeps/unix/bsd/telldir.c: Likewise. * sysdeps/mach/hurd/seekdir.c: Likewise. * sysdeps/mach/hurd/readdir.c: Likewise. * sysdeps/mach/hurd/closedir.c: Likewise. * sysdeps/mach/hurd/opendir.c: Initialize the lock. * sysdeps/unix/opendir.c: Likewise. * sysdeps/mach/hurd/dirstream.h: Include . (struct __dirstream): Add lock member using __libc_lock_define. * sysdeps/unix/dirstream.h: Likewise. * sysdeps/stub/libc-lock.h (__libc_lock_fini): New macro. * stdlib/mbstowcs.c: Pass address of pointer to mbsrtowcs. * stdlib/wcstombs.c: Use wcsrtombs instead of mbsrtowcs. Thu Jul 4 01:34:04 1996 Ulrich Drepper * locale/programs/stringtrans.c: Fix typo in copyright. * stdio-common/printf-prs.c: Add casts to prevent signed<->unsigned warnings. * stdio-common/printf-parse.h: Initialize state variable before calling mbrlen. * stdio-common/printf-prs.c: Don't initialize state variable here. * stdio-common/vfprintf.c: Don't initialize state variable. (vfprintf): While determining length of multibyte string don't try to be clever in determining characters to use for first call. Add real implementation of multibyte<->wide char conversion functions. The functions always convert between the fixed wide char format (ISO 10646 in UCS4) and the UTF8 representation of this character set. Conversion between the currently used 8bit character set and ISO 10646 will not take place. This is what iconv() is for. * wcsmbs/wchar.h (mbstate_t): Define as structure to replace dummy definition. Add optimized version of `mbrlen' function. * wcsmbs/btowc.c (btowc): Restrict range of legal characters to 0...0x7f. * wcsmbs/wctob.c (wctob): Restrict range of legal characters to 0..0x7f. * wcsmbs/mbrlen.c: Make mbrlen a weak alias of __mbrlen. This is needed in the wchar.h header. * wcsmbs/mbrtowc.c: Replace dummy implementation. Convert UTF8 encoded character to UCS4. * wcsmbs/mbsinit.c: Replace dummy implementation. Test COUNT element of `mbstate_t' for initial state. * wcsmbs/mbsrtowcs.c: Replace dummy implementation. Convert UTF8 encoded string to UCS4 string. * wcsmbs/wcrtomb.c: Replace dummy implementation. Convert UCS4 character to UTF8 encoded form. * wcsmbs/wcsrtombs.c: Replace dummy implementation. Convert UCS4 encoded string to UTF8 encoded form. --- sysdeps/mach/hurd/readdir.c | 19 +++++++++++++++---- 1 file changed, 15 insertions(+), 4 deletions(-) (limited to 'sysdeps/mach/hurd/readdir.c') diff --git a/sysdeps/mach/hurd/readdir.c b/sysdeps/mach/hurd/readdir.c index 3c17d248e1..715f9278a2 100644 --- a/sysdeps/mach/hurd/readdir.c +++ b/sysdeps/mach/hurd/readdir.c @@ -1,4 +1,4 @@ -/* Copyright (C) 1993, 1994, 1995 Free Software Foundation, Inc. +/* Copyright (C) 1993, 1994, 1995, 1996 Free Software Foundation, Inc.
