I want to spawn n child processes but have two different classes..with the foremost one forking/spawning the child process and the latter performing a function w/ the spawned processes.

I can do this in one class with an if statement and the simple

if((pid=fork())==0) //child process
{
//do code
}

else
{
//do code as parent process.
}
In doing in w/ two different classes would I need to pass fork() to the slave class? I don't to fork my main process and have it execute the same code as the parent process I want it to execute its own code. That's why I want a separate child/slave class.

also is there a way to JUST spawn children? I don't understand why fork() would create parent processes.
Hopefully my problem isn't too convoluted, thanks.
