The FsRtlPrepareToReuseEcp routine resets an extra create parameter (ECP) context structure, which prepares it for reuse.
EcpContext [in]A pointer to the ECP to prepare for reuse.
The FsRtlPrepareToReuseEcp allows reuse of an ECP used in a previous create request. This prevents having to initialize a new ECP with the same information.
The target of an ECP uses FsRtlAcknowledgeEcp to mark the ECP as acknowledged. This indicates that the ECP was discovered and processed. To reuse a previously acknowledged ECP, such as in processing a reparse, a driver can use FsRtlPrepareToReuseEcp to clear the acknowledged state from the ECP before sending it in another create request.
Within a file system minifilter driver, use FltPrepareToReuseEcp to reuse an ECP.
