Have you tried the retrieve object description API.

Subject: [C400-L] Quickest, easiest way to check for existence of a program, from ILE C?

Would anybody happen to know the quickest, easiest way to check (from an ILE C program) whether a program exists, before attempting to call it?

i.e., if C program FOO has:

 > #pragma linkage(BAR,OS,nowiden)
 > ...
 > int BAR(void *);
 > ...

and wants to call:

 > iretcd = BAR(baz);

but ONLY if BAR actually exists on the system, what's the quickest, easiest, least resource-intensive way to determin whether BAR exists, before calling it?
