pthread_testcancel - request delivery of any pending cancellation request
#include <pthread.h>
void pthread_testcancel(void);
Compile and link with -pthread.
Calling
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.
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.
This function always succeeds.
