Well, true, I do not know for sure what will happen on different platforms, yes - I can't test.
On Linux both work the same way.
Either case, the purpose of qset_acl() is to set ACLs the way so that it corresponds with the mode argument right?
That's what I would expect how it's supposed to work.
If yes, then isn't it better to handle this task to the filesystem driver in kernel and just call chmod?

The "at least in Linux" qualification worries me.
Having a very quick look at the qset_acl() code suggests
it clears ACLs on some platforms at least,
which chmod_or_fchmod() does not.
Am I reading that wrong?

thanks,
