James,

Yes, C has prototypes, but you cannot use an RPG prototype in the C compiler, nor can you use a C prototype in the RPG compiler. I can definitely say that making a set of RPG prototypes that is equivalent to a set of C prototypes (.H) is a somewhat daunting task. A tool to translate a prototype definitions might be very useful, but I'm not aware of any such tools.

Yes, you are correct. I didn't mean to imply that a prototype coded in C could be used by the RPG compiler. Rather that a C function coded with an RPG prototype could be used. Similarly, the C compiler cannot use an RPG coded prototype, but can use an RPG procedure with a C prototype. Sorry for the confusion.

Note that here there is potential trouble. What if you code the prototype incorrectly? Of course this is possible regardless of C. Normally /COPY is used to keep the declarations the same, but you could code a prototype in RPG one way in one source member, then prototype it another way in another source member. It would compile, but Bad Things would happen at run time.
