RE: Calling some vendor "C" code from RPGIV

>Proto currently looks like this:

If I remember, wasn't 'iv' an unsigned long?  If so, you don't want iv to be
an array.

I think this is an RPG question, rather than a C question.  There are more
RPG folks on the RPG list than here on the C list, so if this answer doesn't
help much, perhaps you could pop over there to find more help.  This link
has some information regarding 'translating' C prototypes into RPG; perhaps
it will help http://www.opensource400.com/callc.html
