PTHREAD_TESTCANCEL(3) Linux Programmer's Manual 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_testcancel() has no effect.
RETURN VALUE
This function does not return a value. If the calling thread is can- celed as a consequence of a call to this function, then the function does not return.
ERRORS
This function always succeeds.
