Thread Cancellation [POSIX Section 18]

Functions Implemented

int pthread_cancel(pthread_t thread); 
int pthread_setcancelstate(int state, int *oldstate); 
int pthread_setcanceltype(int type, int *oldtype); 
void pthread_testcancel(void); 
void pthread_cleanup_push( void (*routine)(void *),
                           void *arg); 
void pthread_cleanup_pop( int execute);


Asynchronous cancellation is only partially implemented. In particular, cancellation may occur in unexpected places in some functions. It is strongly recommended that only synchronous cancellation be used.
