Someone can tell me which are the low level step unix makes to make a fork(); (with system call) and returns?

thanks

You can look at the Linux kernel source code. It is very simple :) – Khaled Dec 14 '10 at 15:49

A copy of the process's structures within the kernel is made, along with giving the new process a different PID. The new PID is returned to the caller.

You could elaborate more. The OP wanted a bit more than the successful result of calling fork(). – Tim Post Dec 14 '10 at 15:46
