NAME

       pthread_setcanceltype - set cancellation type of a thread

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_setcanceltype(int type, int *oldtype);

       The  pthread_setcanceltype()  function atomically sets the calling thread's cancellation type to the specified type and, if  oldtype is not
       NULL, stores the previous cancellation type in  oldtype. The  type can be either of the following:

       PTHREAD_CANCEL_DEFERRED	       This is the default. When cancellation is enabled (enabled cancellation is also the default),  cancellation
				       occurs  when  the  target thread reaches a cancellation point and a cancel is pending. When cancellation is
				       disabled, all cancellation requests to the target thread are held pending.

       PTHREAD_CANCEL_ASYNCHRONOUS     When cancellation is enabled, receipt of a  pthread_cancel(3C) call  causes  immediate  cancellation.  When
				       cancellation  is disabled, all cancellation requests to the target thread are held pending; as soon as can-
				       cellation is re-enabled, pending cancellations are executed immediately.

       See cancellation(5) for the definition of a cancellation point and a discussion of cancellation	concepts.  See	pthread_setcancelstate(3C)
       for explanations of enabling and disabling cancellation.

       The  pthread_setcanceltype() function is a cancellation point if type is called with PTHREAD_CANCEL_ASYNCHRONOUS and the cancellation state
       is PTHREAD_CANCEL_ENABLE.

       Upon successful completion, the	pthread_setcanceltype() function returns 0. Otherwise, an error number is returned to indicate the error.

       The  pthread_setcanceltype() function will fail if:

       EINVAL	       The specified type is not PTHREAD_CANCEL_DEFERRED or PTHREAD_CANCEL_ASYNCHRONOUS.
