#ifndef _AIO_H
Update. 1998-06-30 11:47 Ulrich Drepper <drepper@cygnus.com> * include/aio.h: New file. * posix/Makefile (distribute): Add bits/pthreadtypes.h. (tests): Build and run annexc program. * posix/annexc.c: New file. * posix/bits/posix1_lim.h: Add several more _POSIX_* limits. * rt/aio.h: Remove __need_timespec_t. We can include the whole time.h. * rt/aio_misc.c: Include limits.h. * rt/aio_notify.c: Include errno.h. * sysdeps/unix/sysv/linux/alpha/bits/types.h: Include pthreadtypes.h. Define size_t. * sysdeps/unix/sysv/linux/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/bits/types.h: Likewise. * sysdeps/unix/sysv/linux/bits/errno.h: Define ENOTSUP though the kernel doesn't do this. * sysdeps/unix/sysv/linux/bits/fcntl.h: Define O_LARGEFILE only if __USE_LARGEFILE64 is defined. * sysdeps/unix/sysv/linux/bits/pthreadtypes.h: New file. Empty. * sysdeps/unix/sysv/linux/bits/sched.h: Define __sched_param struct if requested. * sysdeps/unix/sysv/linux/bits/siginifo.h: Protect non-standard names. * stdlib/isomac.c: Avoid include_next warning.

y2038: Convert aio_suspend to support 64 bit time The aio_suspend function has been converted to support 64 bit time. This change uses (in aio_misc.h): - __futex_abstimed_wait64 (instead of futex_reltimed_wait) - __futex_abstimed_wait_cancellable64 (instead of futex_reltimed_wait_cancellable) from ./sysdeps/nptl/futex-helpers.h The aio_suspend() accepts relative timeout, which then is converted to absolute one. The i686-gnu port (HURD) do not define DONT_NEED_AIO_MISC_COND and as it doesn't (yet) support 64 bit time it uses not converted pthread_cond_timedwait(). The __aio_suspend() is supposed to be run on ports with __TIMESIZE !=64 and __WORDSIZE==32. It internally utilizes __aio_suspend_time64() and hence the conversion from 32 bit struct timespec to 64 bit one is required. For ports supporting 64 bit time the __aio_suspend_time64() will be used either via alias (to __aio_suspend when __TIMESIZE==64) or redirection (when -D_TIME_BITS=64 is passed).

Linux: Move aio_suspend, aio_suspend64, __aio_suspend_time64 to libc The symbols were moved using scripts/move-symbol-to-libc.py. There is a minor oddity here: This is generic code shared with Hurd, and Hurd does not have time64 support. This is why the versioned_symbol export for __aio_suspend_time64 is restricted to the PTHREAD_IN_LIBC code. Reviewed-by: Adhemerva Zanella <adhemerval.zanella@linaro.org>
