pthread_testcancel - Man Page

request delivery of any pending cancelation request

Library

POSIX threads library (libpthread, -lpthread)

Synopsis

#include <pthread.h>

void pthread_testcancel(void);

Description

Calling pthread_testcancel() creates a cancelation point within the calling thread, so that a thread that is otherwise executing code that contains no cancelation points will respond to a cancelation request.

If cancelability is disabled (using pthread_setcancelstate(3)), or no cancelation 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.
