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

i want to know how it is get connected to the system call.

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). Thanks, Jonathan Neuschäfer
