From 221dc560bb546465befd0a0471f52aa88b69cca6 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Thu, 14 Jun 2001 05:32:26 +0000 Subject: * sysdeps/mach/hurd/fork.c (LOSE): Put `goto lose' in dead code so the label is not considered unused. * sysdeps/mach/hurd/pwrite64.c: New file. * sysdeps/mach/hurd/pread64.c: New file. * sysdeps/mach/hurd/pread.c (__libc_pread): Define this name, with __pread as an alias. * sysdeps/mach/hurd/pwrite.c (__libc_pwrite): Define this name, with __pwrite as an alias. Implement POSIX "shared memory objects" as regular files residing in the /var/run/shm/ directory. This works on any system that supports _POSIX_MAPPED_FILES, to make it also support _POSIX_SHARED_MEMORY_OBJECTS. * sysdeps/posix/shm_open.c: New file. * sysdeps/posix/shm_unlink.c: New file. * sysdeps/mach/hurd/bits/posix_opt.h (_POSIX_SHARED_MEMORY_OBJECTS): Define it. * rt/aio_notify.c (__aio_notify_only) [! _POSIX_REALTIME_SIGNALS]: Use raise instead of __aio_sigqueue. --- rt/aio_notify.c | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) (limited to 'rt/aio_notify.c') diff --git a/rt/aio_notify.c b/rt/aio_notify.c index 558b2d2451..04a9dd6db3 100644 --- a/rt/aio_notify.c +++ b/rt/aio_notify.c @@ -1,5 +1,5 @@ /* Notify initiator of AIO request. - Copyright (C) 1997, 1998, 1999, 2000 Free Software Foundation, Inc. + Copyright (C) 1997,98,99,2000,01 Free Software Foundation, Inc.
