[AFS3-std] rpc refresh: FetchDirectory: discussion only

[Matt W. Benjamin]

Hi Jeff,

I grok all this, and know almost enough to send a better draft later on.

* Ok, so lookup is tangential here, didn't mean to misquote you--when it is useful, is it RXAFS_Lookup as jaltman asked (and just a bitwise comparison)?

* Ok, back to split.

* Ok, let's have client read as much as it wants per call

Yes, I had intended NEntries to mean total entries.  Ambiguous naming aside (and in spite it's being redundant if the client is reading piecewise), is that not useful information for it to have before it begins consuming the stream (though I guess that on re-reading rxgen's manpage, the parameter should have been marked INOUT so it goes in phase 1)?
