It's not entirely clear to me what you want to do. When you fork the pid of the child is returned to parent. Now you want to call a function that returns the pid of a child process "already running". But a child of... what? Do you mean to call this function in the parent? Then you would have better saved it at fork time instead.

Also you want to "get the child pid of a process running, by just passing only the parent process pid". But a parent can have many childs...
