LIST_FOR_EACH_ENTRY_SAFE() will make this shorter.

This leaks 'getloader' on failure. Does this really work though? I should probably be GetObject((void**)object)?
Hello Alistair,
I have two more things: - Parsing of the common chunks is already implemented in IDirectMusicObject_ParseDescriptor(). You can use that; an example is in seg_IPersistStream_Load().
- Please use something like "struct wave_item" instead of "struct DMUS_PRIVATE_WAVE_ITEM". I'm trying slowly to get rid of those DMUS_PRIVATE_*, especially the LPDMUS_PRIVATE_* as it is confusing. While it has PRIVATE in the name it trips me almost every time and I assume a public type. Especially as there are a ton of PRIVATE stuff in the public headers...
thanks bye michael
