So what would you suggest in terms of a filing system address like
/run/user.... ? If your answer is "none of them" then I will stick with
what suits me and leave others to do what they prefer. But if there is a
common and recommended 'location', I can use it.

As I said, use $TMPDIR if set, otherwise use /tmp. It’s a standard
location for temporary files and is often a tmpfs.

If you want your own /tmp to be a tmpfs, do that.

If you want a guarantee that your program will always have a tmpfs
available at some predictable location: sorry, you can’t have one.

As I've said, I'll try to learn about pipes, etc. And I may change
when I learn more. But the reality here at present is that what I've
done seems to work nicely for my purposes. And I thought one of the
strengths of Linux is that we can each use the system as we prefer.

You can do what you like, as I believe I’ve already said. But if you
want your program to integrate well with other people’s systems, there
are right and wrong ways to go about it.
