Or take a look at glibc's implementation. I'm sure you'd be able to find it by downloading glibc and grep'ing it or by searching the web for an online repository with the code.

I don't know exactly where it is, but you could look at
http://repo.or.cz/w/glibc.git.

>From the manpage:
Since version 2.3.3, rather than invoking the kernel's fork()
system call, the glibc fork() wrapper that is provided as part of
the NPTL threading implementation invokes clone(2) with flags
that provide the same effect as the traditional system call. The
glibc wrapper invokes any fork handlers that have been established
using pthread_atfork(3).
