OK, I can write it unless Jan plans to work on it (Jan, please let me know).

I propose to have the usual LTP approach to have functionality used by C API
(e.g. lib/tst_sudo.c) and reused by thin wrapper available for shell API
(testcases/lib/tst_sudo.c).

Few C API tests would use it (prctl06 and other mentioned previously [1] as 3)),
in shell API only these 2 IMA tests.

Agree. I just brought these two topics together as they are related.
So, as a separate topic/effort, do you see any room for C API functions for 1)
and 2) in [1]?

Kind regards,
Petr
