[PLUG] Named pipes


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I'm working on a program running in Linux that is written in Mono. The program
creates an IPC server channel (named pipe) and listens for incoming
communications. I notice that if I create a named pipe using mkfifo it looks
like this in the /tmp file system:
prw-r--r-- 1 root root 0 2010年12月19日 11:50 mkfifo-named-pipe
but when the program runs it creates an entry in the file system that looks like
this:
srw-rw-rw- 1 root root 0 2010年12月19日 11:32 program-named-pipe
Sometimes it appears in the ls output as program-named-pipe=
(with a trailing "=".) What kind of pipe is identified by a leading "s" instead
of "p"?
In any case, I cannot write to that program-named-pipe.
If I try like this:
echo "test" > program-named-pipe
I end up with a regular file by the same name.
Any ideas what I'm seeing? Is this a different kind of named pipe or some
entirely different type of beast?
Thanks,
Eric
