Brendan, after skimming through the rest of the I'm not sure
this is still relevant, but assuming the C struct is correct,
the asn_type is a character, not a pointer to character.  So
the RPG version should just be a 1A, not a *.  But C automatically
aligns structures, so you also have to add the ALIGN keyword
to your RPG DS.  If you don't do that, val_len will be in the
wrong position.  (

This site (Converting C prototypes to RPG) might help, if you are
still doing this in RPG: http://www.opensource400.org/callc.html
(or need to do this kind of translation in the future).
