pthread_testcancel(3) - Linux man page
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 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 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.
Conforming to
POSIX.1-2001.
