Signal Handlers

Hi

I have a program with two forks and a parent process runinng. When ^Z is inputed, if the parent catches it, it kills the children, if a child catches it, it tells the parent and the parent kills the other child.

I am having problems figuring out how to accomplish this.

Should each child share its own handler, or should the parent and both children have a common handler?

Thanks

What you want is kill(). And use SIGUSR1 for your inter-process signalling.
Of course, there many other ways for inter-process communication: pipes, FIFOs, message queues, shared memory, and even sockets (all SVR4 stuff).
