makro

    CLEANUP_HANDLER(sigchld_cancel, &pid, &oldtype);

jest rozwijane przez cos takiego

#define	CLEANUP_RESET(__execute, __oldtype) \
    (void) pthread_cleanup_pop(__execute); \
    (void) pthread_setcanceltype ((__oldtype), &(__oldtype));

w cos takiego

    (void) pthread_setcanceltype (PTHREAD_CANCEL_ASYNCHRONOUS, (&oldtype));
    do {
	__pthread_unwind_buf_t __cancel_buf;
	void (*__cancel_routine) (void *) = ((sigchld_cancel));
	void *__cancel_arg = ((&pid));
	int not_first_call = __sigsetjmp ((struct __jmp_buf_tag *) __cancel_buf.__cancel_jmp_buf, 0);
	if (__builtin_expect (not_first_call, 0))
	{
	    __cancel_routine (__cancel_arg);
	    __pthread_unwind_next (&__cancel_buf);
	}
	__pthread_register_cancel (&__cancel_buf);
    do {;;
