Re: tolua++: passing C++ objects to Lua?

["Leigh McRae" <leigh.mcrae@...>]

TOLUA_API void tolua_pushusertype (lua_State* L, void* value, const char* 
type)

Class Foo;

Foo*    pFoo = new Foo();

tolua_pushusertype( L,  pFoo, "Foo" );

 Off hand I can't remeber how to determine ownership of pFoo.
