IBlockRangeList interface (imapi2.h)
Use this interface to retrieve a list of continuous sector ranges on the media. This interface is used to describe the sectors that need to be updated on a rewritable disc when a new logical session is recorded.
Inheritance
The IBlockRangeList interface inherits from the IDispatch interface. IBlockRangeList also has these types of members:
Methods
The IBlockRangeList interface has these methods.
| IBlockRangeList::get_BlockRanges Returns the list of sector ranges in the form of a safe array of variants of type VT_Dispatch. |
Remarks
IBlockRangeList is returned by the IFileSystemImageResult2::ModifiedBlocks method. Alternatively, IUnknown::QueryInterface can be called on the object returned by IFileSystemImageResult::get_ImageStream to get the list of modified sectors in the result image represented by that object.
The order of sector ranges in IBlockRangeList is taken into account during burning. The sector ranges having lower indexes in the safe array returned by IBlockRangeList::get_BlockRanges are written before those with higher indexes.
