From 0d204b0a522b9fef2168e1808a0566c9209d0893 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Thu, 17 Oct 1996 01:51:38 +0000 Subject: update from main archive 961016 Thu Oct 17 01:55:34 1996 Ulrich Drepper * sunrpc/Makefile ($(objpfx)rpcsvc/%.h, $(objpfx)x%.c): Write output to $@T and move to $@ later since the new rpcgen will not overwrite existing files. * po/Makefile (libc.pot): Fix typo. Sun Oct 13 20:52:07 1996 Thorsten Kukuk Update rpcgen program to TI-rpc code. * sunrpc/Makefile (rpcgen-objs): Add rpc_tblout.o and rpc_sample.o. (distribute): Add proto.h. * sunrpc/proto.h: New file. Prototypes for all the RPC functions. * sunrpc/rpc_clntout.c: Change to allow generation of ISO C code. * sunrpc/rpc_cout.c: Likewise. * sunrpc/rpc_hout.c: Likewise. * sunrpc/rpc_main.c: Likewise. * sunrpc/rpc_parse.c: Likewise. * sunrpc/rpc_parse.h: Likewise. * sunrpc/rpc_scan.c: Likewise. * sunrpc/rpc_scan.h: Likewise. * sunrpc/rpc_svcout.c: Likewise. * sunrpc/rpc_util.c: Likewise. * sunrpc/rpc_util.h: Likewise. * sunrpc/rpc_tblout.c: New file. * sunrpc/rpc_sample.c: Likewise. Thu Oct 17 00:26:20 1996 NIIBE Yutaka * sysdeps/unix/opendir.c: Add semicolon for consistency. Wed Oct 16 12:26:53 1996 Sven Verdoolaege * locale/progams/localedef.c (main): Test with -1 to find out whether read failed. Wed Oct 16 14:54:59 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/i386/clone.S: Use JUMPTARGET and PSEUDO_END macro. Tue Oct 15 21:27:42 1996 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/sigcontext.h: Removed. Tue Oct 15 15:52:29 1996 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/clone.S: Add CALL_MCOUNT. * sysdeps/unix/sysv/linux/m68k/mmap.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sigreturn.S: Likewise. * sysdeps/unix/sysv/linux/m68k/socket.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.S (__errno_location): Likewise. * sysdeps/unix/sysv/linux/m68k/syscall.S: Likewise. Correct generation of system call. Tue Oct 15 15:13:16 1996 Andreas Schwab * Makerules (sysd-Makefile): Fix command so that it works in the subdirectories. (BUILD_CFLAGS): Change back using $(..) instead of $(common-objpfx), the latter fails in the toplevel directory when $(objdir) is relative. (common-objdir-compile): Run compiler in $(objdir). * sysdeps/posix/Makefile (mk-stdiolim): Likewise. Tue Oct 15 23:39:48 1996 Ulrich Drepper * string/string.h [__USE_SVID]: Add prototype for swab. * time/sys/time.h [__USE_BSD]: Add prototype for ualarm. Reported by Andreas Jaeger. The available nlist implementation is not generally usable. Especially on the currently supported ELF systems the nlist function comes with the libelf. * misc/Makefile (headers): Remove nlist.h. (routines): Remove nlist. * Makefile ($(objpfx)version-info.h): Include information about system the libc is built on in version-info.h file. * po/Makefile (distribute): Add header.pot. Tue Oct 15 16:34:15 1996 Andreas Jaeger * sysdeps/unix/sysv/linux/sleep.c: Include file with prototype. * sysdeps/unix/sysv/linux/reboot.c: Likewise. * misc/error.c: Likewise. Tue Oct 15 22:41:27 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/syscalls.list: Add {get,set}resuid.

Sun Oct 13 19:16:10 1996 Andreas Schwab * sysdeps/unix/sysv/linux/m68k/sysdep.h (POUND): Macro removed, replaced by `&'. (PSEUDO_END): Provide definition to use .size directive. (PSEUDO): Don't interpret negative return values less than -128 as syscall error. * sysdeps/unix/sysv/linux/m68k/syscall.S (syscall): Likewise. * sysdeps/m68k/bsd-_setjmp.S: Use PSEUDO_END macro to provide .size directive. * sysdeps/m68k/bsd-setjmp.S: Likewise. * sysdeps/unix/sysv/linux/m68k/clone.S: Likewise. * sysdeps/unix/sysv/linux/m68k/mmap.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sigreturn.S: Likewise. * sysdeps/unix/sysv/linux/m68k/socket.S: Likewise. * sysdeps/unix/sysv/linux/m68k/syscall.S: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.S: Use PSEUDO_END instead of explicit .size directive. * libio/iogets.c: Warn when gets is used. cd * time/strptime.c: Recognize %s, %u, %g, and %G format. --- sunrpc/rpc_svcout.c | 848 +++++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 742 insertions(+), 106 deletions(-) (limited to 'sunrpc/rpc_svcout.c') diff --git a/sunrpc/rpc_svcout.c b/sunrpc/rpc_svcout.c index 7289b0da6e..f959a32b0b 100644 --- a/sunrpc/rpc_svcout.c +++ b/sunrpc/rpc_svcout.c @@ -1,44 +1,47 @@ -/* @(#)rpc_svcout.c 2.1 88/08/01 4.0 RPCSRC */ /* * Sun RPC is a product of Sun Microsystems, Inc. and is provided for * unrestricted use provided that this legend is included on all tape * media and as a part of the software program in whole or part.
