Re: LuaSockets on an embedded platform.

That was not a good reply from me.

loader.preload["socket.core"] = afunction

When you execute require"socket.core" the function at this
table entry is executed. To quote the manual
"To find a loader, first require queries package.preload[modname].
If it has a value, that value (which should be a function) is the loader."

So in your case, I believe that you need

loader.preload["socket.core"] =  luaopen_socket_core

e.g.

  lua_getfield(L, LUA_GLOBALSINDEX, "package");
  if (!lua_istable(L, -1)) {  /* no such field? */
    luaL_error(L, LUA_QL("package") " must be a table");
  	return 0;
  }
  lua_getfield(L, -1, "preload");
  if (!lua_istable(L, -1)) {  /* no such field? */
    luaL_error(L, LUA_QL("package.preload") " must be a table");
  	return 0;
  }
  lua_pushcfunction(L, luaopen_socket_core);
  lua_setfield(L, -2, "socket.core");

Hope this helps.
