    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.
