IFileSystemImageResult2 interface (imapi2fs.h)

The IFileSystemImageResult2 interface allows the data recorder object to retrieve information about modified blocks in images created for rewritable discs. Alternatively, IUnknown::QueryInterface can be called on the object returned by IFileSystemImageResult::get_ImageStream to get the IBlockRangeList interface providing this information.

Inheritance

The IFileSystemImageResult2 interface inherits from IFileSystemImageResult. IFileSystemImageResult2 also has these types of members:

Methods

The IFileSystemImageResult2 interface has these methods.

IFileSystemImageResult2::get_ModifiedBlocks Retrieves the list of modified blocks in the result image.

Remarks

When the file system image object is used to append data to a rewritable disc, the result image contains both the previous logical session and the new additions. The result image represents the binary data that must be recorded to disc starting from sector 0 to get a disc containing both old and new files. However, the previous logical session remains mostly intact during addition of new files, so the burn time can be substantially optimized by recording only the sectors that are new or have been modified.
