Subject: Killing a background process from a C program

I am in the process of converting a Bourne shell script to C, and I am
having trouble finding out how to identify and kill background
processes.  With the Bourne Shell approach this was simple, using $!.

What I would like to do is start a background process at one point in the
C program, and at a later time kill it.  Currently I am invoking the
background process with system("background_process &");, but none of the
texts that I have available help me to proceed any further.

Any assistance would be appreciated.
