As a further historical note, originally 9P required a stream that preseved
record boundaries, and the reliable datagram protocol IL/IP and pipes did
that. Once TCP/IP was used, there was some fussing needed to work out where
the records were, so the revision 9P2000 added a size and the stream
Zero conventionally means end-of-file, but record boundaries are preserved
on capable streams, so if a writer writes zero, the reader reads zero.
Having said that, I think the comment is wrong, and read9pmsg returning
zero should be interpreted as the end of the (9p) stream.
In most cases, the

However this two requirements do not seem reconcilable.

I can't see how a reliable communication (a cpu connection for example) can
survive this mismatch.
I'm probably missing something.
A specialised reader and writer can always

I wrote a little rc script for my personal use. I want to share it with you, as

Hi, I've a probably naive question that I can't figure out.
I've just noticed that fcall(2) states
Read9pmsg calls read(2) multiple times, if necessary, to
read an entire 9P message into buf. The return value is 0
for end of file, or -1 for error; it does not return partial
messages.
but
on plan 9 systems 0 writes are not discarded.
