The FltPrepareToReuseEcp routine resets an extra create parameter (ECP) context structure, which prepares it for reuse.
- Filter [in]
An opaque filter pointer for the minifilter driver. This pointer uniquely identifies the minifilter driver and remains constant as long as the minifilter driver is loaded.
- EcpContext [in]
A pointer to the ECP to prepare for reuse.
The FltPrepareToReuseEcp 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 FltAcknowledgeEcp 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 FltPrepareToReuseEcp to clear the acknowledged state from the ECP before sending it in another create request.
