Here is the source I was browsing: glibc source. My particular question arises from this particular set of functions: socket library.

For example(most of the functions are set up this way) socket/bind.c's source is:

  19 #include <errno.h>
  20 #include <sys/socket.h>
  21 
  22 /* Give the socket FD the local address ADDR (which is LEN bytes long).  */
  23 int
  24 __bind (fd, addr, len)
  25      int fd;
  26      __CONST_SOCKADDR_ARG addr;
  27      socklen_t len;
  28 {
  29   __set_errno (ENOSYS);
  30   return -1;
  31 }
  32 
  33 weak_alias (__bind, bind)
  34 
  35 stub_warning (bind)
  36 #include <stub-tag.h>

I admit I didn't spend a lot of time, but where exactly is the code for the actual function and what is going on? Is this a well used paradigm?
