The ClfsLsnLess routine determines whether one LSN is less than another LSN. The two LSNs must be from the same stream.
plsn1 [in]A pointer to a CLFS_LSN structure that supplies one of the LSNs to be compared.
plsn2 [in]A pointer to a CLFS_LSN structure that supplies the other LSN to be compared.
ClfsLsnLess returns TRUE if plsn1 is strictly less than plsn2; otherwise, it returns FALSE.
CLFS_LSN_NULL (the smallest LSN) and CLFS_LSN_INVALID (larger than any valid LSN) are valid arguments to ClfsLsnLess.
LSNs from different streams are not comparable. Do not use ClfsLsnEqual, ClfsLsnLess and the like to compare LSNs from different streams.
