Folks:
I've been assigned the task of find an API or C routine that replaces a MI
program we currently use to set the file level id for PF's & LF's.
We want to replace the MI routine because it won't run on a system at level
40 security.
Here's the current routine ... I have absolutely NO idea what it's going...
if someone can point me to an API or C routine that can do the same thing,
it would be greatly appreciated.
Thanks!
david
