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

       Callingpthread_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 (usingpthread_setcancelstate(3)), or       no cancelation request is pending, then a call topthread_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.
