The SANE specification tells me that the form of sane_control_option is:
sane_control_option (SANE_Handle h, SANE_Int n, SANE_Action a,
void *v, SANE_Int * i);
Also, it tells me that "[t]his function is used to set or inquire the
current value of option number n of the device represented by handle h."
It is the n that I am confused about. Specifically, what does n = 0 mean?
