int
pthread_condattr_destroy (
         pthread_condattr_t   *attr);

This routine destroys a condition variable attributes object (the object becomes uninitialized).

Condition variables that were created using this attributes object are not affected by the deletion of the condition variable attributes object.

After calling this routine, the results of using attr in a call to any routine (other than pthread_condattr_init) are unpredictable.

If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows:

Return Description
