From d41c6f6161ef2b500b68d7599fcbc6a4c4ca2285 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Sun, 13 Oct 1996 21:35:39 +0000 Subject: update from main archvie 961013 Sun Oct 13 22:52:56 1996 Ulrich Drepper * shlib-versions: Add version number/name for ld.so. * Makeconfig: Move definition of rtld-installed-name after inclusion of soversions.mk. Don't add . before version number from shlib-versions file when when name does not start with digit. This is needed for ld.so. Sat Oct 12 20:31:58 1996 Richard Henderson * libio/iogets.c: Warn when gets used. * stdio/gets.c: Strengthen the warning. Sat Oct 12 23:10:43 1996 Ulrich Drepper * libio/Makefile [_LIBC_REENTRANT] (routines): Add peekc. * libio/libio.h: Add prototypes for _IO_getc, _IO_putc, _IO_feof, _IO_ferror, _IO_peekc_locked, and _IO_ftrylockfile. Remove prototypes for _IO_getc_locked and _IO_putc_locked. [_IO_MTSAFE_IO]: Add weak aliases for _IO_flockfile and _IO_funlockfile. [! _IO_MTSAFE_IO]: Define _IO_ftrylockfile as empty. Define _IO_getc, _IO_peekc, _IO_putc, _IO_feof, _IO_ferror to appropriate values according to __USE_REENTRANT. * libio/stdio.h: Add prototype for ftrylockfile. [!_LIBC]: Define getc_locked, getchar_locked, putchar_locked, getc, getchar, putc, and putchar using _IO_* names. * libio/feof.c: Rename to _IO_feof and make feof weak alias. * libio/ferror.c: Rename to _IO_ferror and make ferror weak alias. * libio/getc.c: Rename to _IO_getc and make getc weak alias. * libio/putc.c: Rename to _IO_putc and make putc weak alias. * libio/putc_u.c: Don't define alias _IO_putc_unlocked. * libio/peekc.c: New file. * stdio-common/vfprintf.c (vfprintf): Unconditionally call __flockfile. * sysdeps/stub/locfile.c [USE_IN_LIBIO]: Also define _IO_* names. * crypt/Makefile (tests): Add md5test and md5c-test. * crypt/md5-crypt.c: Correct various error. Now md5_process_bytes is called, the buffer limit is honoured and a loop in a inner loop is corrected. * crypt/md5.h (struct md5_ctx): Add new fields. Add prototypes for new functions. * crypt/md5.c (md5_init_ctx): Initialize new fields. (md5_finish_ctx): New function. Like md5_read_ctx but before perform correct finalization. (md5_process_bytes): New function. Similar to md5_proces_block, but does not require input size to be multiple of 64. (md5_stream): Rewrite using md5_process_bytes and md5_finish_ctx. (md5_buffer): Likewise. (md5_process_block): Count number of bytes. * crypt/md5test.c: New file. Test program for MD5 functions. * crypt/md5c-test.c: New file: Test program for MD5 crypt function. * po/fr.po: Update. * time/strptime.c: Recognize %s, %u, %g, and %G format. * posix/getopt.c: Add some more casts and initializations to prevent warnings. Sat Oct 12 16:15:29 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/speed.c (speeds): Removed. We provide an extra function to provide this functionality. (cfgetospeed): Simply return masked value. (cfsetospeed): Don't use speeds array and so we can simply test the value of SPEED for illegal values. * termios/cfsetspeed.c: Rewrite. We convert here between the real values and the B* constants. Changes suggested by Uwe Ohse . Fri Oct 11 21:45:34 1996 Andreas Jaeger * locale/programs/xstrdup.c: Define prototypes. * locale/programs/xmalloc.c: Likewise. * stdio-common/xbug.c (main): Change definition to avoid warning. Fri Oct 11 23:36:31 1996 Miles Bader * db/hash/hash.c (__hash_open): Correctly test for a read-write db. --- libio/peekc.c | 41 +++++++++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) create mode 100644 libio/peekc.c (limited to 'libio/peekc.c') diff --git a/libio/peekc.c b/libio/peekc.c new file mode 100644 index 0000000..2b0a812 --- /dev/null +++ b/libio/peekc.c @@ -0,0 +1,41 @@ +/* +Copyright (C) 1993, 1995, 1996 Free Software Foundation, Inc. + +This file is part of the GNU IO Library.
