[sane-devel] scanner buttons

[Gerhard Jaeger]

Hi Rene,

I'm somewhat curious on your implementation ;-) How will you solve this?
Are you using some kind of background process or thread to update
peridodically the status? What is the callback, or the corresponding
sane_ function, that a frontend can use?

Ciao,
  Gerhard
