Conventions for function success definitions

I was hoping someone would be able to fill me in on the proper way to define success codes similar to S_OK and S_FALSE. I created my own definitions as shown below in MyApp.h
#define DEBUG_MODE ((HRESULT)0x00000040L)
#define S_FOUND ((HRESULT)0x00000050L)
#define S_EMPTY ((HRESULT)0x00000060L)
I simply copied the definition for S_OK and modified the name and number which seems amateurish at best. How should I do this properly?

Many thanks,

You should use the macro "MAKE_HRESULT".  Here is the documentation:

For your custom results, you should use the facility "FACILITY_ITF" which is reserved for custom interfaces.  Then, use "SEVERITY_SUCCESS" to indicate success.  The final parameter can be anything that you want.


That's the "proper" way to do it.

Hope That Helps,

Cheers, that worked perfectly except FACILITITY_ITF should be FACILITY_ITF ;)

Thanks again,
Heh...  Spelling was never my forté.  I even spelled it right the first time I mentioned it...  Oh, well...  Glad you got it working...
