man pthread_cancel:

pthread_setcanceltype  changes  the  type  of responses to cancellation
requests for the calling thread: asynchronous (immediate) or  deferred.

The  type  argument  is  the new cancellation type: either

 PTHREAD_CANCEL_ASYNCHRONOUS 

to cancel the calling thread as soon as the  cancellation  request  is
received, or

 PTHREAD_CANCEL_DEFERRED 

to keep the cancellation request pending until the next cancellation
point.
