* DESCRIPTION
* This function creates a deferred cancellation point
* in the calling thread. The call has no effect if the
* current cancelability state is
* PTHREAD_CANCEL_DISABLE
*
* NOTES:
* 1) Cancellation is asynchronous. Use pthread_join
* to wait for termination of thread if necessary

* RESULTS
