Since fork() is only supported in a single-threaded application, you
generally don’t need pthread_atfork().
What are you trying to accomplish?

Thank you very much !
Actually,after going through the documentation of pthread_atfork(),I was
trying to create a deadlock situation and to solve it using
pthread_atfork().
All this is for my information only.

I would suggest that the document page for pthread_atfork() be amended
to reflect the fact that this function can not actually be used in a
multi-threaded QNX6 system.

But pthread_atfork() can be used… and, I’m pretty sure will cause the
appropriate handlers to be called.

Yes, but fork() itself will fail… :v)
