Some dmusic questions

[Rok Mandeljc]

Today I did some "tests" with dmusic; I've tried to run dxdiag with
mixture of builtin and native dm*.dll and I have some questions based on
observations:

1. dm*.dlls don't share DllGetClassObject function like I did in wine's
implementations (dm*.dlls other than dmusic.dll have their functions
forwarded to dmusic.dll). Shall we implement such separation or shall we
leave it as it is? (personally, I'd choose separation because then
mixing dlls would be more efficient; at the moment, all dm*.dlls call
dmusic.DllGetClassObject, which mean I must replace all of them with
native equivalents if I want to replace dmusic.dll; besides, dxdiag
crashes in a mysterious way with builtin dlls and I expect the problem
lies here).

2. when listing dmusic ports, dmusic calls EnumLegacyDevice, which is
stub, because I can't find any info about it's parameters... It calls
some winemm stuff and lists Wine midi out mapper, although it can't be
used. It is obvious that it lists devices that could be used as ports,
except Microsoft Software Synthesizer, which is available only if native
dmsynth.dll is used (i used native dmusic.dll). Any ideas where I could
get more detailed info about what does this funct. do and what
parameters it takes?


3. this one concerns RIFF loading stuff I've been working on recently.
MSDN states that IStream and IPersistStream insterfaces should be used
in parsing data, which means all functs. in helper.c are wrong. I'll
look deeper into docs and try to find out how it's supposed to go (just
expect that all functs. will be replaced so do not modify them ;=) ).

"All that is gold does not glitter,
Not all those who wander are lost;
The old that is strong does not wither,
Deep roots are not reached by the frost. 
From the ashes a fire shall be woken,
A light from the shadows shall spring;
Renewed shall be blade that was broken,
The crownless again shall be king."
