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.
