If you are waiting for a specific child temrimatingin see 'waitpid(); (or
wait4() - "man wait4") -- that safes you the while() loop. It allows you
to listen for just the child you want.

If you just want to -know- if a child dies but simply allow your program
to continue then install a signal handler on SIGCHLD.

The best book I personally found is to get is "Advanced Programming in the
UNIX Environment" by Richard Stevens.
