You can't ask Lua to convert a number to userdata, and that's what the
second parameter is. I don't understand what you're really trying to do,
but if you want to access a raw number as a void* (what seems really
weird in this context), just cast it *after* converting to a lua number
(e.g. "(void*)lua_tonumber(L, 2)").
