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.
CONFORMING TO
       POSIX.1-2001.
EXAMPLE
       See pthread_cleanup_push(3).
