[sane-devel] Doubt about sane_get_devices

[tobias alarcon]

Hi all

Im just wanna know if this function retrives the list of devices at
every moment.
Let me explain, i launch my program with the scanner disconected, then
i conect it and
call this function. Doc say "This function can be called repeatedly to
detect when
new devices become available" but this is not my case, i get a null pointer.

thanks in advance
Tobias.
