/* sigh... now comes track creation... currently I have some problems with implementing
this one because my test are contradicting:
- tracks are not loaded by loader (at least my dxdiag test with native dmime doesn't show it)
therefore i guess they're created with CoCreateInstance with CLSID specified in header and
IID_IDirectMusicTrack(8). Tracks are then probably passed to IDirectMusicSegment_Insert
(not quite sure, but behaviour complies with the one described in MSDN (about calling IDirectMusicTrack_Init)
- but on the other hand, track's stream implementation gets only <data> chunk (look in MSDN for more info)
(tested with native dmime and builtin dmband and dmstyle) => this means that all info about track (header, extra header
UNFO, GUID and version are read by segment's stream... now, how the hell is all this info set on track?!
=> I believe successful approach would be to create structure like this:
_DMUSIC_PRIVATE_TRACK_ENTRY {
DMUS_IO_TRACK_HEADER trkHeader;
DMUS_IO_TRACK_EXTRAS_HEADER trkXHeader;
WCHAR* name, ...;
GUID guidID;
DMUS_VERSION vVersion;
...
IDirectMusicTrack* pTrack;
} DMUSIC_PRIVATE_TRACK_ENTRY;
and then load all stuff into it
=> anyway, I'll try to implement it when I find some time again, but this note is here for anyone that wants to give it a try :)
