PTHREAD_COND_TIMEDWAIT(3) BSD Programmer's Manual PTHREAD_COND_TIMEDWAIT(3)
pthread_cond_timedwait - wait on a condition variable for a specific
amount of time
#include <pthread.h>
int
pthread_cond_timedwait(pthread_cond_t *cond, pthread_mutex_t *mutex,
const struct timespec *abstime);
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.
If successful, the pthread_cond_timedwait() function will return zero.
Otherwise an error number will be returned to indicate the error.
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.
pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3),
pthread_cond_signal(3), pthread_cond_wait(3)
pthread_cond_timedwait() conforms to ISO/IEC 9945-1:1996 ("POSIX").
