glibc/sunrpc/xdr_sizeof.c
Ulrich Drepper 7d1de115db Update.
1999-03-08  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/ttyname.c (ttyname): Undo last change.
	/dev/pts status may change during runtime.

1999-03-08  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/ttyname_r.c (__ttyname_r): Undo last
	change.  /dev/pts status can change during runtime.

1999-03-07  Thorsten Kukuk  <kukuk@suse.de>

	* sunrpc/svc_tcp.c (readtcp): go into fatal error state if
	poll reports error.
	* nis/nss_nisplus/nisplus-parser.c: Avoid duplicate strlen calls,
	add some more sanity checks.
	* nis/nss_nisplus/nisplus-pwd.c: Include nisplus-parser.h for
	parser prototype.

1999-03-05  Thorsten Kukuk  <kukuk@suse.de>

	* sunrpc/rpc/xdr.h: Add x_getint32/x_putint32 to xdr_ops,
	change XDR_GETINT32/XDR_PUTINT32 to sue new functions.
	* sunrpc/xdr_mem.c: Add xdrmem_getint32, xdrmem_putint32.
	* sunrpc/xdr_rec.c: Add xdrrec_getint32, xdrrec_putint32.
	* sunrpc/xdr_sizeof.c: Add x_putint32, add dummy function
	for x_getint32.
	* sunrpc/xdr_stdio.c: Add xdrstdio_getint32, xdrstdio_putint32.
	* nis/nis_print.c: Fix ctime argument for platforms where
	sizeof (time_t) != sizeof (int).

	255.  Patch by Bruno Haible <haible@ilog.fr> [PR libc/1010].
