I recently saw this function in one of the online test paper i was going through. And i came to know that this is a standard library function but i dont know anything about it. And it is related to some Parent process - Child process kind of things. And I don't know about them too.
Please explain these three things and their use!

It is a standard POSIX function. It is not a standard C/C++ function.

See Wikipedia for more. Be sure to click on the first few links down at the bottom in the "See Also" section too.

Hope this helps.

fork() only for *nix operating systems, MS-Windows doesn't support it.

ok i got it..thanks to all for the help..
