Arnaud,
I have a question regarding the below structure you've added:
> typedef struct usb_device_id_t {
> int vendorID;
> int productID;
> void*(*fun)(); /* handler for specific processing */
> } usb_device_id;
I don't understand the last element in this structure. While there can
be plenty of reasons for functions returning (void *), I can't figure
out what use this could possibly have here.
Since this structure is supposed to be used as input to
is_usb_device_supported() and that function returns an (int), what can
we possibly do with the return value of (void *)(*fun)()? Using that,
would require casting the (void *) pointer to something useful, but
how would we tell this to is_usb_device_supported()? Could it be you
actually meant (void)(*fun)(), ie a function that doesn't take
parameters and returns nothing?
Best regards, Arjen
