WDF_REQUEST_FORWARD_OPTIONS structure (wdfrequest.h)
[Applies to KMDF only]
The WDF_REQUEST_FORWARD_OPTIONS structure contains options for requeuing an I/O request from a child device's I/O queue to the parent device's I/O queue.
Syntax
typedef struct _WDF_REQUEST_FORWARD_OPTIONS {
ULONG Size;
ULONG Flags;
} WDF_REQUEST_FORWARD_OPTIONS, *PWDF_REQUEST_FORWARD_OPTIONS;
Members
Size
The size, in bytes, of this structure.
Flags
A bitwise OR of WDF_REQUEST_FORWARD_OPTIONS_FLAGS-typed flags.
Remarks
The WDF_REQUEST_FORWARD_OPTIONS structure is used as input to the WdfRequestForwardToParentDeviceIoQueue method.
Your driver must call WDF_REQUEST_FORWARD_OPTIONS_INIT to initialize the WDF_REQUEST_FORWARD_OPTIONS structure before the driver calls WdfRequestForwardToParentDeviceIoQueue.
