PTHREAD_COND_TIMEDWAIT(3)

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

LIBRARY
libc_r

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 requires 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.
