Condition variable to be destroyed.
This routine destroys the condition variable specified by cond. This effectively uninitializes the condition variable. Call this routine when a condition variable will no longer be referenced. Destroying a condition variable allows DECthreads to reclaim internal memory associated with the condition variable.
It is safe to destroy an initialized condition variable upon which no threads are currently blocked. Attempting to destroy a condition variable upon which other threads are blocked results in unpredictable behavior.
The results of this routine are unpredictable, if the condition variable specified in cond does not exist or is not initialized.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The value specified by cond is invalid. The object being referenced by cond is being referenced by another thread that is currently executing pthread_cond_wait(3) or pthread_cond_timedwait(3) on the condition variable specified in cond.
Functions: pthread_cond_broadcast(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3), pthread_cond_wait(3)
