How could I embedded socket in Lua internally, just like oslib, debuglib?

[sagasw <sagasw@...>]

I want to implement the function like embedding the socket function in my Lua build.
So I don't need to copy socket.core.dll any more (just for fun).

I search the maillist, and see some guys discuss the topic,

http://lua-users.org/lists/lua-l/2005-10/msg00269.html

But I have question for the details steps, who could give me a detailed steps for changing the lua and luasocket code to make them work together (not with dll method).

I tried these steps in windows xp with VC2008:
1) copy luasocket code to Lua project.
2) add some code 
static const luaL_Reg lualibs[] = {
  {"", luaopen_base},
  {LUA_LOADLIBNAME, luaopen_package},

  {LUA_TABLIBNAME, luaopen_table},
  {LUA_IOLIBNAME, luaopen_io},
  {LUA_OSLIBNAME, luaopen_os},
  {LUA_STRLIBNAME, luaopen_string},
  {LUA_MATHLIBNAME, luaopen_math},
  {LUA_DBLIBNAME, luaopen_debug},
  {LUA_SOCKETLIBNAME, luaopen_socket_core}, // add this line
  {LUA_MIMELIBNAME, luaopen_socket_core}, // add this line
  {NULL, NULL}
};

3) build the project, and run it.
When I type “print(socket._VERSION)", it shows "luasocket 2.0.2", it is correct.

When I type "print(socket.dns.toip("localhost"))", it shows "127.0.0.1  table: 00480AD0", it is correct too.

But when I try to use other features, for example bind, it can't work.

Who could tell me the reason, thanks,
