return void function

[David Anderson]

Your comment about 
  return RpcRaiseException(hr);
is quite interesting, but, IMO, it's not a good choice.

 RpcRaiseException(hr);
 return;
is c-like whereas 
 return RpcRaiseException(hr); 
is a (slightly arcane)
C++-ism which, I gather, really only came about because template/generic
programming sort of forces it to be legal else various
templates could not be written.

The original ANSI C expressly forbids your return
statement under 'constraints'
of section 6.6.6.4 (ISO/IEC 9899 section numbering in this sentence).

I think the original questions demonstrate that 
it would be better written as simpler C as I suggest (and others
hinted). 

David Anderson: just making a suggestion here.
