Generic notification of process death - why not?
Hi,
I'm pretty sure this has been asked before, but I cannot find the answer.
In QNX4, a process could set the _PPF_INFORM process flag to receive a message from the kernel whenever any process died
.
In QNX6, there is no such mechanism any longer - at least not for being informed of the death of _any_ process for _any_
reason. We can only get notification under certain conditions - for session 1, for child processes, for client
processes connected to us, or for processes terminating abnormally.
Is there a specific reason that the process manager does not provide a generic process death notification mechanism? If
so, what is that reason?
Thanks in advance,
Thomas
