Clarification wrt. lua_newuserdata()

[Marc Balmer <marc@...>]

So when my C function that is called from Lau does a  "lua_newuserdata()“ followed by by a function that pushes a value on the stack, e.g. "lua_pushinteger(L, 42)“, the stack will contain the userdata object and the number 42 on top.  When I return 1, it will return the number value to Lua and the userdata value just below it will eventually be garbage collected, right?
