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.
