kick starting lua_next()

["Marius Gheorghe" <mgheorghe@...>]

Being in a tight spot (thus preferring not to have to look at the source
code) I thought of asking these questions to the list, maybe someone knows
already the answer and has the time to post it here.

1) Does lua_next() have to be always kick started by using lua_pushnil() or
is it acceptable to push any key and the traversal will commence from that
key?

2) If the answer to the above is true (pushing a key other than nil is
acceptable), will lua_next() work if the key is not present in the table
being traversed?

Thank you.
