glibc/hurd/vpprintf.c
Roland McGrath b4e54243c4 * mach/devstream.c (devstream_write, devstream_read): New functions.
(input, output): Functions removed.
	(mach_open_devstream): Use devstream_{read,write} as cookie functions,
	using only the vanilla fopencookie interface.

	* hurd/fopenport.c [! USE_IN_LIBIO] (cookie_io_functions_t): Define
	as macro for __io_functions.
	(funcsio): Use cookie_io_functions_t type name.
	(fopenport): Renamed from __fopenport.  Rewrite to call fopencookie.

	* libio/iofopncook.c (_IO_cookie_init): New function, broken out of
	fopencookie.
	(fopencookie): Use it.
	* libio/libio.h: Declare _IO_cookie_init.
	* hurd/vpprintf.c (vpprintf) [USE_IN_LIBIO]: Implement using
	_IO_cookie_init.

	* libio/libio.h (__io_seek_fn): Fix second argument type
	to be a pointer, in line with the manual and the old stdio.
	* libio/iofopncook.c (_IO_cookie_seek): Fix (sole) caller.

	* sysdeps/generic/bits/stdio-lock.h: New file.
	This is a stub with #error, but that's better than no file at all.

	* sysdeps/unix/sysv/linux/alpha/syscall.S:
	* manual/message.texi (Using gettextized software):
	* manual/filesys.texi (File Size):
	* manual/charset.texi (glibc iconv Implementation):
	* locale/programs/ld-collate.c (collate_output):
	* manual/stdio.texi (Output Conversion Syntax):
