Checking if Table is Empty (C API)

[Marc Lepage <mlepage@...>]

In Lua a good way to check if a table t is empty is to check if next(t) == nil.

What is the best way to check if a table is empty using the C API? Is it basically the same technique?

    // table is on stack at index t

    lua_pushnil(L); // nil key

    if (lua_next(L, t))
    {

        // not empty

        lua_pop(L, 2);

    }

    else
    {

       // empty

    }

Or is there a better way?
