Re: Problem with userdata (metatable)

["Anders Bergh" <anders@...>]

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
Segmentation fault
