Pull a Handler Off the Stack

pthread_cleanup_pop(3T)

Use pthread_cleanup_pop(3T) to pull the cleanup handler off the cleanup stack.

A nonzero argument in the pop function removes the handler from the stack and executes it. An argument of zero pops the handler without executing it.

pthread_cleanup_pop() is effectively called with a nonzero argument if a thread either explicitly or implicitly calls pthread_exit(3T) or if the thread accepts a cancel request.

Prototype:
void pthread_cleanup_pop(int execute);

#include <pthread.h>

/* pop the "func" out of cleanup stack and execute "func" */
pthread_cleanup_pop (1);

/* pop the "func" and DONT execute "func" */
pthread_cleanup_pop (0); 

There are no return values.
