how to catch child program using signals

Hello All,


I have a program(process) creating a new process after a long run with the PPID of my program(even name was same).

Can I catch this child program using signal handlers?

What all the possible reasons for the same situation ?


Thanks in advance
Ashok

I am not the expert but I believe the ONLY reason for this to occur is if you are using fork() or threads. Are you (or are you using a library which does?)

Actually I have a main program, that creates a Thread, because of unknown reasons the thread is creating another thread (extra) (extra Thread has the Ppid of the earlier thread)

I'm not using any fork() system call here.

Environment ---- architecture: powerpc Linux kernel : 2.4


I really have no clue why this happening, and not able to reproduce it.
Its happening after a long run of the program.


what might be the reason?


Thanks
