Library that has reference to fork() in C

Question

What is the library that defines fork(). I am learning to use fork(). I found out that the Standard I/O Library : stdio.h is enough for fork() to work but that

Answer 1

I am using gcc in Code::Blocks on Windows 8 Pro

You don't have fork on windows. You can use cygwin or something like that though.

Answer 2

The C standard library (glibc) implements fork() which calls a UNIX/Linux-specific system call eventually to create a process, on Windows, you should use the winapi CreateProcess() see this example in MSDN.

Note: Cygwin fork() is just a wrapper around CreateProcess() see How is fork() implemented?
