PTHREAD_COND_TIMEDWAIT(3) OpenBSD Programmer's Manual
						     PTHREAD_COND_TIMEDWAIT(3)

NAME
     pthread_cond_timedwait - wait on a condition variable for a specific
     amount of time

SYNOPSIS
     #include <pthread.h>

     int
     pthread_cond_timedwait(pthread_cond_t *cond, pthread_mutex_t
     *mutex, const struct timespec *abstime);

DESCRIPTION
     The pthread_cond_timedwait() function atomically blocks the current
     thread waiting on the condition variable specified by cond, and unblocks
     the mutex specified by mutex.  The waiting thread unblocks only after
     another thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3)
     with the same condition variable, or if the system time reaches the time
     specified in abstime, and the current thread reacquires the lock on
     mutex.

RETURN VALUES
     If successful, the pthread_cond_timedwait() function will return zero.
     Otherwise an error number will be returned to indicate the error.

ERRORS
     pthread_cond_timedwait() will fail if:

     [EINVAL]	   The value specified by cond, mutex or abstime is invalid.

     [ETIMEDOUT]   The system time has reached or exceeded the time specified
		   in abstime.

SEE ALSO
     pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3),
     pthread_cond_signal(3), pthread_cond_wait(3)

STANDARDS
     pthread_cond_timedwait() conforms to ISO/IEC 9945-1:1996 (``POSIX'').
