IMO, the user-land programs need to be build with the matched
headers separately.

You absolutely cannot provide this new interface to userland and
expect programs to be able to just use it, it's non-standard and does
not exist in older headers.

Got it, sorry for my mistake, and thanks for your correction.

I do not want this new interface available to userland programs.
They can just open-code the list traversal just like every program
in history has had to do since BSD UNIX.

Agree. Let's leave the user-land ones as they are.
I'll send a new version (without changing user-land ones) soon.

Best regards,
Gu
