If fork was successful, then there are now two processes, both executing the main function from the point where fork has returned. To make the processes perform different tasks, the program must branch on the return value of fork to determine whether it is executing as the child process or the parent process.
fork() is the name of the system call that the parent process uses to "divide" itself ("fork") into two identical processes. After calling fork(), the created child process is an exact copy of the parent except for the return value of the fork() call. This includes open files, register state, and all memory allocations, which includes the ...
The death of the fork. This is by far the most common case. It is easy to declare a fork, but considerable effort to continue independent development and support. A re-merging of the fork (e.g., egcs becoming "blessed" as the new version of GNU Compiler Collection.) The death of the original (e.g. the X.Org Server succeeding and XFree86 dying.)
In 2012, the Gentoo Linux project created a fork of udev in order to avoid dependency on the systemd architecture. The resulting fork is called eudev and it makes udev functionality available without systemd. [122] A stated goal of the project is to keep eudev independent of any Linux distribution or init system.

In parallel computing, the fork–join model is a way of setting up and executing parallel programs, such that execution branches off in parallel at designated points in the program, to "join" (merge) at a subsequent point and resume sequential execution.
A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace. In computing, a system call (commonly abbreviated to syscall) is the programmatic way in which a computer program requests a service from the operating system [a] on which it is executed.
Canada is a beautiful country and an outdoors lover's paradise, with national parks such as Banff and amazing winter sports in Whistler.. But outside Quebec and a handful of other provinces ...
The Gunicorn "Green Unicorn" (pronounced jee-unicorn or gun-i-corn) [2] is a Python Web Server Gateway Interface (WSGI) HTTP server. It is a pre-fork worker model, ported from Ruby's Unicorn project. The Gunicorn server is broadly compatible with a number of web frameworks, simply implemented, light on server resources and fairly fast. [3]
