The ClfsLsnBlockOffset routine returns the sector-aligned block offset contained in a specified LSN.
ULONG ClfsLsnBlockOffset( _In_ const CLFS_LSN *plsn );
A pointer to a CLFS_LSN structure from which the block offset is retrieved.
ClfsLsnBlockOffset returns the block offset contained in the LSN that is supplied by the caller.
The block offset returned by this routine is a multiple of the sector size on the stable storage medium. For example, if the sector size is 1024 bytes, the block offset is a multiple of 1024.
