Re: [9fans] Porting to plan9 / PF_UNIX

["Francisco J Ballesteros" <nemo@lsub.org>]

If you want a program to serve something for others, there are several ways.
One way would be to write a file server, and register with srv(3) one
end of a pipe
that others could mount. There are plenty of examples in /sys/src/cmd.
I'd suggest to go over the manual seeking for programs that might do something
similar to what you want, and then reading their code.
