The WDF_REQUEST_REUSE_PARAMS structure specifies information that is associated with a reused I/O request.
SizeThe size, in bytes, of this structure.
FlagsA bitwise OR of one or more WDF_REQUEST_REUSE_FLAGS-typed flags.
StatusAn NTSTATUS value that the framework assigns to the request.
NewIrpA pointer to an IRP structure. This member's value is optional and can be NULL.
The WDF_REQUEST_REUSE_PARAMS structure is used as input to WdfRequestReuse.
To initialize this structure, the driver must call WDF_REQUEST_REUSE_PARAMS_INIT. To set a NewIrp value in the structure, the driver must call WDF_REQUEST_REUSE_PARAMS_SET_NEW_IRP after calling WDF_REQUEST_REUSE_PARAMS_INIT.
If a lower driver needs to access the Status value, it can find it in the Irp->IoStatus.Status field.
You can set a NewIrp value only if the I/O request that you supply to WdfRequestReuse was created by calling WdfRequestCreate or WdfRequestCreateFromIrp.
