Hello,
currently, the sanei_usb_find_devices() and
sanei_usb_attach_matching_devices() functions use an attach callback which
has only a 'name' parameter. So when parsing configuration options quite a
few backends store options in global vars to use them at attach time. Now we
have a SANEI_Config structure, I'd like to add it to the parameters so that
we can pass it to attach function and avoid the use of global vars.
This would made the use of sanei_configure_attach() even simpler, since
a
backend would only need this attach with config struct callback to work. USB
backends with no options would even only need to add this parameter (leaving
it unused) to their current attach function and call
sanei_configure_attach().
Since I suppose backend maintainers would rather avoid their backend
modified
to add an unused parameter. I'm thinking about duplicating these two
sanei_usb functions.
Would it be OK that way ?
Regards,
Stef
