One solution that I have employed is to define my own exit routine.
When the program terminates my exit routine is called, and does what
I want.

	void exit(e)
		int e;
	{
		...whatever...
		_exit(e);	/* still need this sucker */
	}

This probably is non-portable but should solve your problem (if I
understood it correctly).

If you have the source code to popen(3) look at it for another example.
