ClfsLsnEqual function (wdm.h)

The ClfsLsnEqual routine determines whether two LSNs from the same stream are equal.

Syntax

C++

CLFSUSER_API BOOLEAN ClfsLsnEqual(
  [in] const CLFS_LSN *plsn1,
  [in] const CLFS_LSN *plsn2
);

[in] plsn1

A pointer to a CLFS_LSN structure that supplies one of the LSNs to be compared.

[in] plsn2

A pointer to a CLFS_LSN structure that supplies the other LSN to be compared.

ClfsLsnEqual returns TRUE if the two LSNs are equal; otherwise, it returns FALSE.

CLFS_LSN_NULL (the smallest LSN) and CLFS_LSN_INVALID (larger than any valid LSN) are valid arguments to ClfsLsnEqual.

LSNs from different streams are not comparable. Do not use ClfsLsnEqual, ClfsLsnGreater, and the like to compare LSNs from different streams.
