That will work fine - if the client program including it has only one
source file #including this header. If more than one file includes it,
you'll get multiple definitions of the GUID and a linker error.
If you don't like the INITGUID mess, another approach is to put your
GUIDs in a static LIB which the client program can link to.

Subject: [directmusic] DMO COM question
So, I finally have a working beta version of my low-pass 2 pole resonant
filter DMO. It works in DMP, I can get its interfaces in code and tweak
it=20
real-time, my audiopaths can reference it and load it, and it works on
other=20
peoples' machines (only tested on XP so far)! Very soon I'll put it up
for=20
dload so that I can get some feedback (and free testing) from you lot.
But first, a quick question for the DirectX / COM code gurus:
I'd like to distribute LPF_DMO.h with the .dll in order to expose the=20
interface to DirectMusic programmers. The DEFINE_GUID macro seems like
a=20
bit of a pain for users though, what with all the Initguid.h and "can
only=20
be initialized once" shenanigans.
Is there any reason why I can't just provide this in my header instead?
const GUID IID_ILPF_DMO =3D
{ 0xd841b97f, 0x5d83, 0x4d76, { 0x90, 0x13, 0xed, 0x83, 0x4, 0xa, 0xe2,
0xa3=20
} };
Thanks,
Andrew
