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 in abstime.
