You can call the module functions just like in Lua. For example to do:

require 'socket'
s = socket.tcp()

you can write the following C code:

lua_getglobal(L, "require");
lua_pushstring(L, "socket");
lua_call(L, 1, 0);
lua_getglobal(L, "socket");
lua_getfield(L, -1, "tcp");
lua_replace(L, -2);
lua_call(L, 0, 1);
lua_setglobal(L, "s");
