Uh.

You're forking with fork(), I assume? So you're probably using the standard forking idiom

if (my $pid = fork()) { # do stuff in the parent } else { # do stuff in the child }

or a variant thereof.

The return value of fork() is, according to the perldoc, undef if the fork failed, 0 if the fork succeeded and you're in the child process, or the child's PID if the fork succeeded and you're in the parent process. So the parent process gets the forked process' PID as fork()'s return value. You can collect these every time you fork and manage your child processes however you want.
