Controls how records are scanned. The constants are passed to CreateLogContainerScanContext, and have the following possible values.

Constant/value Description

Causes the next call to ScanLogContainers to proceed in a forward direction.
Cannot be used if CLFS_SCAN_BACKWARD is specified.

Causes the next call to ScanLogContainers to proceed in a backward direction.
Cannot be used if CLFS_SCAN_FORWARD is specified.
CLFS_SCAN_CLOSE

Uninitializes the scan context, and deallocates system storage that is associated with a scan context.
CLFS_SCAN_INITIALIZED
0x10
Indicates that the scan context is already initialized.

Indicates that the scanned container descriptors are pre-fetched and buffered.
