pthread_testcancel(3)    Library Functions Manual   pthread_testcancel(3)

NAME         top

       pthread_testcancel - request delivery of any pending cancelation
       request

LIBRARY         top

       POSIX threads library (libpthread, -lpthread)

SYNOPSIS         top

       #include <pthread.h>

       void pthread_testcancel(void);

DESCRIPTION         top

       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         top

       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         top

       This function always succeeds.
