Managing Threads Exit

#include <pthread.h>
void pthread_cleanup_push(void (*routine)(void *), void *arg);
void pthread_cleanup_pop(int execute);

• The function pthread_cleanup_push() pushes a cleanup handler onto the calling thread's stack of cleanup handlers. When the handler is later invoked, the arg value will be passed to it.

• The function pthread_cleanup_pop() pops the handler at the top of the cleanup stack and optionally executes it if the execute argument is nonzero.
