[ILUG] Signal handling

[Dale Dunlea]

Hi All,

I have a program which calls execl to fork a child process. I have a
signal handler that does the needful when said process exits. Lovely.

But sometimes bad things happen. Sometime programs crash. But the pid of
the child process is stored and so when the program restarts, it knows
the pid of the child process of its previous instance. I need to install
a signal handler in the new program instance for the old child process -
to reparent it essentially. I presume there is a way of doing this, but
I'm quite new to process control and all that.

Thanks in advance,
Dale.
