Fork (system call): Standards, Variants & Overview

In computing, fork is an operation whereby a process creates a copy of itself. It is usually implemented as a C standard library wrapper to the fork, clone, or other system calls of the kernel. For many years, fork was the primary method of process creation on Unix and Unix-like operating systems, and it remains a required interface for compliance with…
