There is no length parameter.<br>
If you just wish to count the devices, loop through it until you get
to a NULL pointer.<br>
<br>
You can find an example in the SANE backends source for scanimage:
frontend/scanimage.c around line 2184.<br>
<br>
Have you read the SANE API spec?<br>
If not, it is here:<br>
