/* SIDE NOTES:
|
|
* After extensive testing and structure dumping I came to a conclusion that
|
|
* DirectMusic as in present state implements three types of streams:
|
|
* 1. IDirectMusicLoaderFileStream: stream that was most obvious, since
|
|
* it's used for loading from files; it is sort of wrapper around
|
|
* CreateFile, ReadFile, WriteFile and SetFilePointer and it supports
|
|
* both read and write
|
|
* 2. IDirectMusicLoaderResourceStream: a stream that had to exist, since
|
|
* according to MSDN, IDirectMusicLoader supports loading from resource
|
|
* as well; in this case, data is represented as a big chunk of bytes,
|
|
* from which we "read" (copy) data and keep the trace of our position;
|
|
* it supports read only
|
|
* 3. IDirectMusicLoaderGenericStream: this one was the most problematic,
|
|
* since I thought it was URL-related; besides, there's no obvious need
|
|
* for it, since input streams can simply be cloned, lest loading from
|
|
* stream is requested; but if one really thinks about it, input stream
|
|
* could be none of 1. or 2.; in this case, a wrapper that offers
|
|
* IDirectMusicGetLoader interface would be nice, and this is what this
|
|
* stream is; as such, all functions are supported, as long as underlying
|
|
* ("low-level") stream supports them
|
