void WDF_USB_CONTROL_SETUP_PACKET_INIT_VENDOR(
  [out] PWDF_USB_CONTROL_SETUP_PACKET Packet,
  [in]  WDF_USB_BMREQUEST_DIRECTION   Direction,
  [in]  WDF_USB_BMREQUEST_RECIPIENT   Recipient,
  [in]  BYTE                          Request,
  [in]  USHORT                        Value,
  [in]  USHORT                        Index
);

Parameters

[out] Packet

A pointer to a WDF_USB_CONTROL_SETUP_PACKET structure.

[in] Direction

A WDF_USB_BMREQUEST_DIRECTION-typed value that is stored in the Packet.bm.Request.Dir member of the WDF_USB_CONTROL_SETUP_PACKET structure.

[in] Recipient

A WDF_USB_BMREQUEST_RECIPIENT-typed value that is stored in the Packet.bm.Request.Recipient member of the WDF_USB_CONTROL_SETUP_PACKET structure.

[in] Request

A request type constant that is stored in the Packet.bRequest member of the WDF_USB_CONTROL_SETUP_PACKET structure.

[in] Value

A request-specific value that is stored in the Packet.wValue.Value member of the WDF_USB_CONTROL_SETUP_PACKET structure.

[in] Index

A request-specific index value that is stored in the Packet.wIndex.Value member of the WDF_USB_CONTROL_SETUP_PACKET structure.

Return value

None

Remarks

The WDF_USB_CONTROL_SETUP_PACKET_INIT_VENDOR function does the following:

  • Zeros the WDF_USB_CONTROL_SETUP_PACKET structure.
  • Sets the Packet.bm.Request.Type member to BmRequestVendor.
  • Sets other structure members by using the WDF_USB_CONTROL_SETUP_PACKET_INIT_VENDOR function's input arguments.
To initialize a WDF_USB_CONTROL_SETUP_PACKET structure, the driver should call one of the following functions: The following code example initializes a WDF_USB_CONTROL_SETUP_PACKET structure. 
WDF_USB_CONTROL_SETUP_PACKET  controlSetupPacket;

WDF_USB_CONTROL_SETUP_PACKET_INIT_VENDOR(
                                         &controlSetupPacket,
                                         BmRequestHostToDevice,
                                         BmRequestToDevice,
                                         USBFX2LK_REENUMERATE,
                                         0,
                                         0
                                         );
