Where is the Linux socket implementation implemented?

Question

In C programs, to use sockets, we need to enable:

#include<sys/socket.h>

I searched the file socket.c(implementation <sys/socket.h>) but did not find it ( find -iname "socket.c*")

• Where can I find a Linux socket implementation?
• Can I change this file and change this implementation?
