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 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_cancel() 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.

EXAMPLE
See pthread_cleanup_push(3).
