_CLS_SCAN_CONTEXT structure

-description

The CLFS_SCAN_CONTEXT structure holds context information to support a scan of the containers in a Common Log File System (CLFS) log. The client allocates this structure by calling ClfsCreateScanContext. Then, the client passes the structure repeatedly to ClfsScanLogContainers.

-struct-fields

-field cidNode

A CLFS_NODE_ID structure that contains the scan context's node identity and type.

-field plfoLog

A pointer to a LOG_FILE_OBJECT structure that represents a CLFS log.

-field cIndex

The index of the current container.

-field cContainers

The number of containers to scan in each call to ClfsScanLogContainers. This is the number of elements in the array pointed to by pinfoContainer.

-field cContainersReturned

The number of containers actually scanned in a call to ClfsScanLogContainers.

-field eScanMode

This member can be one of the following values.

Value Meaning
CLFS_SCAN_INIT The scan is reinitialized and begins at the first container in the container list.
CLFS_SCAN_FORWARD The next set of containers is scanned.
CLFS_SCAN_BACKWARD The previous set of containers is scanned.
CLFS_SCAN_CLOSE The scan is closed. No containers are scanned.

-field pinfoContainer

A pointer to an array of CLFS_CONTAINER_INFORMATION structures. The cContainers parameter specifies the number of elements in this array.
