Forget it. sys$getuai is a 32 bit system service and can't handle 64 bit addresses,
so you have to move the data to a temp buffer in 32 bit space. See the openvms
programming concepts manual, chapter 11 (support for 64 bit addressing).

When I compiled, linked, and ran it, it exited with
"Status is 98994" which, being translated, means %RMS-E-RNF, record not
found.

This does not surprise me in the least since there is no user NAGARAJ in
my UAF.

When I run it with a username that exists in my UAF, it fails with an
ACCVIO.

I hope this provides you with a clue!

I will leave further debugging as a exercise for the student.
