Re: Quickest, easiest way to check for existence of a program, from ILE C?

It's possible for ILE C to call using a system pointer. You could use one of the _RSLVSP MI builtins to find the program, and then if successful, use the pointer that it returns to make the call.

Just a thought.

i.e., if C program FOO has:

and wants to call:

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?
