glibc/io/sys/stat.h
Ulrich Drepper 99e46354d9 Update. 
1998-10-13  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c: Include
	string.h to get memcpy prototype and NULL definition.

1998-10-12  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* misc/sys/cdefs.h (__THROW): New macro.
	* argp/argp.h: Use it to replace the kludgey __P in inline
	function definitions.
	* sysdeps/unix/sysv/linux/bits/socket.h: Likewise.
	* stdlib/stdlib.h: Likewise.
	* wcsmbs/wchar.h: Likewise.
	* libio/stdio.h: Likewise.
	* stdio/stdio.h: Likewise.
	* sysdeps/wordsize-64/inttypes.h: Likewise.
	* sysdeps/wordsize-32/inttypes.h: Likewise.
	* string/argz.h: Likewise.
	* io/sys/stat.h: Likewise.

1998-10-12  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* Rules (stdio_lim): New variable.
	($(stdio_lim:h=st)): Use this as intermediate stamp file, depend
	on Rules and config.make, use $(move-if-change) to avoid unnessary
	recompilations, and cleanup command.
	(common-generated): Add bits/stdio_lim.st.

wrappers around calls to `xstat', `fxstat', `lxstat', and `xmknod',
which all take a leading version-number argument designating the
data structure and bits used. <bits/stat.h> defines _STAT_VER with
the version number corresponding to `struct stat' as defined in
that file; and _MKNOD_VER with the version number corresponding to
the S_IF* macros defined therein. It is arranged that when not
inlined these function are always statically linked; that way a
dynamically-linked executable always encodes the version number
corresponding to the data structures it uses, so the `x' functions
in the shared library can adapt without needing to recompile all
callers. */
