Since I don't use top, I wouldn't know... if the modern-top definition is not described there, you could, I dunno, *reproduce* it?

It defines ORIG_TOPDEFS which gets used in places like https://gitlab.com/procps-ng/procps/blob/55a42ae040eaa19fd3089f56d98ccbde5a9abc3a/top/top.h#L251 > Did I miss something obvious?

I didn't suggest that, I suggested the new top interface could almost certainly be reimplemented if you know the right top options... probably by like reading documentation. I consider top to be an exercise in frustration, so won't try myself, but analyzing top.h as I referenced would probably let you do this. :) -- Eli Schwartz Bug Wrangler and Trusted User
