Author: davidxu Date: Tue Aug 17 02:50:12 2010 New Revision: 211409 URL: http://svn.freebsd.org/changeset/base/211409 Log: Tweak code a bit to be POSIX compatible, when a cancellation request is acted upon, or when a thread calls pthread_exit(), the thread first disables cancellation by setting its cancelability state to PTHREAD_CANCEL_DISABLE and its cancelability type to PTHREAD_CANCEL_DEFERRED. The cancelability state remains set to PTHREAD_CANCEL_DISABLE until the thread has terminated. It has no effect if a cancellation cleanup handler or thread-specific data destructor routine changes the cancelability state to PTHREAD_CANCEL_ENABLE.
