*
* Suffixing an "I" indicates that the macro should emit a dummy
* procedure name in RDEBUG because the interface is internal.
*
* End a procedure with one of the following:
*
* ExitProc();
*
* Procedure returns no value.
*
* ExitProcX();
*
* Procedure returns an arbitrary DWORD.
*
* ExitOleProc();
