Hope this helps.
Note that when you declare something like:
a =Account(100);
a is already a pointer to the class Account.
I presume this is what you are looking for:
If i'm wrong, please be more specific.
static int check( lua_State *L) {
Account* a =checkAccount( L, 1);
int amount =( int)luaL_checknumber( L,2 );
a->check( amount);
return 0; // supose Account::check doesent return any value
}
static Account* checkAccount( lua_State* L, int narg) {
luaL_checktype( L, narg, LUA_TUSERDATA);
void* ud =luaL_checkudata( L, narg, className);
if( ! ud)
luaL_typerror( L, narg, className);
return *( Wrapper**) ud; // unbox pointer
}
