Correction, it returns the child-process id to the parent process.
And, it returns 0 to the child process.

On failure, it returns -(ve) value only to the parent process, which is
logical as no child process is created.

If you're going to post a followup, please don't start a new thread.

If you're going to discuss fork(), please post to
comp.unix.progr ammer, not comp.lang.c.

Thanks.

Correction, it can return anything, because it's not part of
standard C. On my Whizbang3 OS, it returns an array of pointers
to foods best eaten with a fork, and takes an optional parameter
to include spork matches in the results.

Hi I want to have a wait page while the rest of the cgi does its process, but it seems like the wait page waits till everything is complete and never appears. I've tried forking twice already as suggested in a faq, but it still doesnt seem to work. Below is what I have done: pid = fork() if (pid == 0){ printf ("http://my.wait.page"); exit (100);

Now before I go into detail I just want to say that this is purely for my own benefit and has no real world usage. I remember way back when the tool for *nix systems called forkbomb was created. I recently explained it to a friend of mine and at that time decided to see if I could replicate it in C#. I have created an application that, to me at least, mimics what fork would/should do on *nix/bsd systems. I know that fork spawns a new...

when the fork system call is executed, a new process is created. The original process is called the parent process whereas the new process is called the child process. The new process consists of a copy of the address space of the parent. On success, both processes continue execution at the instruction after the fork call, with one difference, the return code for the fork system call is zero for the child process, while the process identifier of...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
