clfs.h contains the following programming interfaces:

Functions

ClfsLsnEqual Determines whether two LSNs from the same stream are equal.
ClfsLsnGreater Determines whether one LSN is greater than another LSN. The two LSNs must be from the same stream.
ClfsLsnLess Determines whether one LSN is less than another LSN. The two LSNs must be from the same stream.
ClfsLsnNull Determines whether a specified LSN is equal to the smallest possible LSN, which is CLFS_LSN_NULL.

Structures

CLFS_NODE_ID Represents a node identifier.
CLS_ARCHIVE_DESCRIPTOR Used by the GetNextLogArchiveExtent function to return information about log archive extents.
CLS_CONTAINER_INFORMATION Describes general information about a container.
CLS_INFORMATION Describes general information about a log.
CLS_IO_STATISTICS Defines the statistics that are reported by GetLogIoStatistics.
CLS_IO_STATISTICS_HEADER Header for information retrieved by the GetLogIoStatistics function, which defines the I/O performance counters of a log.
CLS_LSN Represents a valid log address.
CLS_SCAN_CONTEXT The CLS_SCAN_CONTEXT structure contains information about the containers that are being scanned by ScanLogContainers.
CLS_WRITE_ENTRY Contains a user buffer, which is to become part of a log record, and its length.

Enumerations

CLFS_CONTEXT_MODE Specifies a context mode type that indicates the direction and access methods that a client uses to scan a log.
CLFS_IOSTATS_CLASS Defines types of I/O statistics reported by CLFS and is used when a client calls GetLogIoStatistics.
CLFS_LOG_ARCHIVE_MODE Specifies whether a log is ephemeral.
