pthread_testcancel: request delivery of any pending cancellation request
pthread_testcancel - request delivery of any pending cancellation request
#include <pthread.h> void pthread_testcancel(void); Compile and link with -pthread.
DESCRIPTIONCalling pthread_testcancel() creates a cancellation point within the calling thread, so that a thread that is otherwise executing code that contains no cancellation 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 VALUEThis 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.
ERRORSThis function always succeeds.
