PTHREAD_COND_TIMEDWAI... BSD Library Functions Manual PTHREAD_COND_TIMEDWAI...

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 *restrict cond,
         pthread_mutex_t *restrict mutex,
         const struct timespec *restrict 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 spec-ified specified
                        ified 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.1'').
