pthread_testcancel (3)

#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.

Multithreading (see pthreads(7))

The pthread_testcancel() function is thread-safe.

POSIX.1-2001.
