Hmm, I tried this:
struct user *llua_pushuser (lua_State *L, struct user *user_ptr) {
struct user **l_user = (struct user**)lua_newuserdata(L,
sizeof(struct user*));
*l_user = user_ptr;
luaL_getmetatable(L, TYPE);
lua_setmetatable(L, -2);
return *l_user; /* is this right? using return l_user made gcc say
warning: return from incompatible pointer type */
}
Output:
PrintUserInfo: 0x8158a4c
-> nick: ÐØ
-> numeric: ¸øí·
-> oper: 96
