PTHREAD_TESTCANCEL(3) Linux Programmer's Manual PTHREAD_TESTCANCEL(3) NAME pthread_testcancel - request delivery of any pending cancellation request SYNOPSIS #include <pthread.h> void pthread_testcancel(void); Compile and link with -pthread. DESCRIPTION Calling pthread_testcancel() creates a cancellation point within the calling thread, so that a thread that is otherwise executing code that contains no cancellaβ tion points will respond to a cancellation request. If cancelability is disabled (using pthread_setcancelstate(3)), or no cancellation request is pending, then a call to pthread_testcancel() has no effect. RETURN VALUE This function does not return a value. If the calling thread is canceled as a consequence of a call to this function, then the function does not return. ERRORS This function always succeeds.
