- Subject: Cancellation points
I'm having some problems working out which functions are cancellation points
pthread_cancel() with pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, NULL).
I'm using pthreadsVC.dll on Windows 2000.
Is Sleep() meant to be a cancellation point in WIN32? I've read in the
manual that sleep() and usleep() are cancellation points for pthreads on
Solaris, but can
not find a list of cancellation points for pthreads on WIN32.
Also pthread_mutex_lock() is acting as a cancellation point in my code. I
have to put
pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, NULL) before my
calls to pthread_mutex_lock to stop it acting as a cancellation point. If
cancellation occurs in a call to pthread_mutex_lock(), the mutex that was
returns EBUSY when destroyed with pthread_mutex_destroy(). Has anyone else
seen this happen?
Thanks for any help,
