View the official Windows Driver Kit DDI referenceNo description available.
The FltSetEcpListIntoCallbackData routine attaches an extra create parameter context structure (ECP) list to a create operation callback-data object.
Filter [in]Opaque filter pointer to the minifilter driver. This pointer uniquely identifies the minifilter driver and remains constant as long as the minifilter driver is loaded.
CallbackDataPointer to a callback-data object of type FLT_CALLBACK_DATA, which represents the create operation.
EcpList [in]Pointer to the ECP list, which contains one or more ECPs, to be attached to the callback-data object.
FltSetEcpListIntoCallbackData returns one of the following NTSTATUS values:
| Return code | Description |
|---|---|
| STATUS_SUCCESS | The given ECP list was successfully attached to the given callback-data object. |
| STATUS_INVALID_PARAMETER_2 | The given callback data object was not an IRP-based create operation. |
| STATUS_INVALID_PARAMETER_3 | An ECP list has already been attached to the given callback-data object. |
The FltSetEcpListIntoCallbackData routine provides a mechanism for passing extra create parameters down the file system filter stack to underlying minifilter and legacy filter drivers.
To retrieve an attached ECP list from a given callback-data object, use the FltGetEcpListFromCallbackData routine.
