SANE question

Hi,

I'm trying to implement using SANE within Scribus and I'm hitting a small
snag. While the majority of the API is really simple to use, I'm having a
problem with what SANE_Handle is.

The sane.h header has it defined as

typedef void *SANE_Handle;

There are plenty of functions which require SANE_Handle, but nothing which
actually sets it!

According to the sane website, SANE does not require that a value of this
type be a legal pointer value and an application shouldn't attempt to
interpret the value of SANE_Handle.

This doesn't make sense - it looks like I can quite happily send "flibble"
as the handle and it makes no difference (okay, I know that's not the
case...).

How should I set the handle. For instance, when I obtain the device list,
I have two show for my USB webcam and one for my scanner. I have to be
able to set the handle to the scanner. Is it enough to set the handle to
the device name or should it be set to the physical /dev/sg0 value (which
is not a good idea!)

TTFN
