This is obvious, I'm trying to understand "Accessing". Do you mean
unparse the specified parts or update/set it? For what use-case?

We have something like this for command line (misc-utils/uuidparse.c).

$ uuidparse $(uuidgen --time)
UUID                                  VARIANT TYPE       TIME
970f197e-ba55-11ec-aa93-43a3097bca4a  DCE     time-based 2022-04-12 13:42:11,097843+02:00


Do you mean anything like;

     uuid_time_get_version(uuidstr);
     uuid_time_get_clock_seq()
     ...

or the same but for already parsed uuid (uuid_t)?
