RE: Pop Return results after pcall'ing

["Jerome Vuarand" <jerome.vuarand@...>]

All return values are discarded after being used. There is no such problem with the stack size, you don't have to manage anything in your C functions.

And on the other hand you cannot use the stack as a storage place for your objects. If you want them to be preserved after the call to your C function you have to put them in some table.

Objet : Pop Return results after pcall'ing

I've previously asked about whether function parameters are automatically pop'ed off the stack after the function call
(http://lua-users.org/lists/lua-l/2006-03/msg00074.html) but what happens if you don't pop the returned values after you have finished with them.  I assume that the stack will simple grow indefinitely until you run out of memory?
