IVssExamineWriterMetadata class (vsbackup.h)
The IVssExamineWriterMetadata interface is a C++ (not COM) interface that allows a requester to examine the metadata of a specific writer instance. This metadata may come from a currently executing (live) writer, or it may have been stored as an XML document.
An IVssExamineWriterMetadata interface to a live writer's metadata is obtained by a call to IVssBackupComponents::GetWriterMetadata.
Metadata obtained from a stored XML document can be examined by an instance of IVssExamineWriterMetadata obtained by a call to CreateVssExamineWriterMetadata.
