* Name: pthread_setcancelstate
*
* Description:
* The pthread_setcancelstate() function atomically both sets the calling
* thread's cancelability state to the indicated state and returns the
* previous cancelability state at the location referenced by oldstate.
* Legal values for state are PTHREAD_CANCEL_ENABLE and
* PTHREAD_CANCEL_DISABLE.
*
* The cancelability state and type of any newly created threads,
* including the thread in which main() was first invoked, are
* PTHREAD_CANCEL_ENABLE and PTHREAD_CANCEL_DEFERRED respectively.
*
