NAME
pthread_testcancel - 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.
