NAME

    pthread_cond_destroy - Deletes a condition variable

 SYNOPSIS

     #include <pthread.h>

     int pthread_cond_destroy(pthread_cond_t *cond);

 PARAMETERS

     cond                Condition variable deleted.

 DESCRIPTION

 The pthread_cond_destroy() routine deletes a condition variable. Call
 this routine when a condition variable is no longer referenced. The
 effect of calling this routine is to give permission to reclaim storage
 for the condition variable.

 The results of this routine are unpredictable if the condition variable
 specified in cond does not exist.

 The results of this routine are also unpredictable if there are threads
 waiting for the specified condition variable to be signaled or broadcast
 when it is deleted.

 RETURN VALUES

 If the function fails, errno may be set to one of the following values:

    Return   Error      Description
    ___________________________________________________________
     0                  Successful completion.

    -1      [EINVAL]    The value specified by cond is invalid.

    -1      [EBUSY]     A thread is currently executing a
                        pthread_cond_timedwait() routine or
                        pthread_cond_wait() on the condition
                        variable specified in cond.
