About `remote-tty'

[Xue Fuqiao]

In (info "(elisp) Process Information"):

 -- Function: process-tty-name process
[...]
     If PROCESS represents a program running on a remote host, the
     terminal name used by that program on the remote host is provided
     as process property `remote-tty'.

What does "process property" mean here?

It seems that it's not an overlay property or a text property, maybe
it's a symbol property.  I've used `M-x apropos', searched the archives
and manuals, but nothing helped.  I'd like to read the source code, but
I'm not familiar with process.c.

Maybe it means the properties in `process-plist'?

I think so.

A plist is a property list. See

(info "(elisp) Property Lists")

or

http://emacswiki.org/emacs/AlistVsPlist

A bit down in the info node you quoted this is mentioned:

   Every process also has a property list that you can use to store
miscellaneous values associated with the process.

 -- Function: process-get process propname
     This function returns the value of the PROPNAME property of
     PROCESS.

 -- Function: process-put process propname value
     This function sets the value of the PROPNAME property of PROCESS
     to VALUE.

 -- Function: process-plist process
     This function returns the process plist of PROCESS.

Thank you.  I'll add an `@cindex' to processes.texi.
