By attaching buffers for isochronous transfer with 1394 device, the
ISOCH_DESCRIPTOR structure is used for describing a buffer to be attached or
detailed from a resource handle.

There is a another structure named 'R3 ring descriptor'.

Could somebody help me to understand this structure?

What describes this structure?

thanks in advance

Perhaps you could give us a little hint as to where you found this. I
couldn't find any such thing in the DDK.

Note that "ring 3" means user mode, so this might be a structure used to
make an application request.

Thanks for your reply and sorry, I was not detailed enough. I'll post with
more details by next time.

Here is a document about R3 ring descriptor :

p.s Thanks for your note about 'ring 3'. It helped me a lot to understand
it. So far I have understood, the application saves informations
in R3 ring descriptor first, and then the driver copies it in
isoch_descriptor.
