Add:
int pthread_cond_clockwait (pthread_cond_t *cond,
pthread_mutex_t *mutex,
clockid_t clockid,
const struct timespec *abstime)
which behaves just like pthread_cond_timedwait except it always measures
abstime against the supplied clockid. Currently supports CLOCK_REALTIME
and
CLOCK_MONOTONIC and returns EINVAL if any other clock is specified.
Includes feedback from many others. This function was originally
proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group
preferred the new name.
* nptl/Makefile: Add tst-cond26 and tst-cond27
* nptl/Versions (GLIBC_2.30): Add pthread_cond_clockwait
* sysdeps/nptl/pthread.h: Likewise
* nptl/forward.c: Add __pthread_cond_clockwait
* nptl/forward.c: Likewise
* nptl/pthreadP.h: Likewise
* sysdeps/nptl/pthread-functions.h: Likewise
* nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Add
clockid parameter and comment describing why we don't need to
check
its value. Use that value when calling
futex_abstimed_wait_cancelable rather than reading the clock
from
the flags. (__pthread_cond_wait): Pass unused clockid parameter.
(__pthread_cond_timedwait): Read clock from flags and pass it to
__pthread_cond_wait_common. (__pthread_cond_clockwait): Add new
function with weak alias from pthread_cond_clockwait.

Pass
CLOCK_USE_ATTR_CLOCK for existing tests, and add new tests using
all combinations of CLOCK_MONOTONIC and CLOCK_REALTIME.
* ntpl/tst-cond26.c: New test for passing unsupported and
* invalid
clocks to pthread_cond_clockwait.
* nptl/tst-cond27.c: Add test similar to tst-cond5.c, but using
struct timespec and pthread_cond_clockwait.
* manual/threads.texi: Document pthread_cond_clockwait. The
* comment
was provided by Carlos O'Donell.
