alien question: how to get the address of a buffer object?

[Cosmin Apreutesei <cosmin.apreutesei@...>]

Hi,

Is there a way to get the address of a buffer object? I need to store
the address of a buffer in a structure that I'll pack with
alien.struct.pack. The only solution I have found till now involves
creating another buffer just to store and later retrieve the address
of the first one.

Thanks,
Cosmin.

PS: Hope it's ok to ask questions related to lua libraries on this
list (or should I go to luaforge?)
