Oh, I see. That does make sense. Thank you.
I failed to make the connection that the stat
buffer itself is considered a variable length
field (including the size).
One last niggle -- intro(5), paragraph 4, sentence 3
could stand to have "of larger or" removed since
the 13 byte w?qid doesn't have a two-byte size.
Just curious, but why isn't data in Rread and Twrite
a variable length field with a two-byte count? Count was
two bytes in 2nd Ed 9P; what was the motivating push
for four bytes?
I suppose it does allow you to reserve count values
~0 through ~0-6 for special meaning, though this seems
unexploited.
Cheers,
Sam
