Hi pankaj,
In Windows, threads get cancelled only in CANCELLATION POINTS.
So you *cannot* expect your thread to get cancelled as soon as you cancel
the thread
by calling pthread_cancel. So,unless it comes across a cancellation point
it wont get cancelled.
I suggest you to do a explicit pthread_testcancel() in your thread which is
a defined cancelleation point
and the thread will relinquish when it encounters this.
some possible scenarios where a thread might not get cancelled are

> waiting for a user input from console(getchar())
regds,

Do I have to something more??
Can I have a sample code??
Thanks

Thanks Srikanth
Are there any system define cancellation points like
sleep, pthread_cond_wait, read, write etc
When did thread actually get cancelled???
When a running thread encounter a cancellation point
after pthread_cancel is called???
Or if a thread gets cancel when we are in system a
system define canecllation point??
Thanks again....
Regards
Pankaj
