Destroying the Condition Variable State

Use pthread_cond_destroy(3C) to destroy any state that is associated with the condition variable pointed to by cv.

pthread_cond_destroy Syntax

int pthread_cond_destroy(pthread_cond_t *cv);

#include <pthread.h>

pthread_cond_t cv;
int ret;

/* Condition variable is destroyed */
ret = pthread_cond_destroy(&cv); 

Note that the space for storing the condition variable is not freed.
