NAME



pthread_cond_timedwait

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

LIBRARY

Lb libpthread

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 Fa cond , and releases the mutex specified by Fa mutex . The waiting thread unblocks only after another thread calls pthread_cond_signal3, or pthread_cond_broadcast3 with the same condition variable, or if the system time reaches the time specified in Fa abstime , and the current thread reacquires the lock on Fa 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

The pthread_cond_timedwait ();
function will fail if:

Bq Er EINVAL: The value specified by Fa cond , Fa mutex or Fa abstime is invalid.
Bq Er ETIMEDOUT: The system time has reached or exceeded the time specified in Fa abstime .
Bq Er EPERM: The specified Fa mutex was not locked by the calling thread.
