[Applies to KMDF and UMDF]
The WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB function initializes a WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure so that a driver can select a USB interface by specifying a URB.
Params [out]A pointer to a driver-allocated WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure.
Urb [in]A pointer to a URB structure.
The WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB function zeros the WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure and sets its Size member to the size of the structure. It also sets the Type member to WdfUsbInterfaceSelectSettingTypeUrb and sets the Types.Urb.Urb member to the value that is specified by Urb pointer.
To initialize a WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure, your driver must call one of the following functions:
The following code example initializes a URB structure and then uses the structure as input to WdfUsbInterfaceSelectSetting.
WDF_USB_INTERFACE_SELECT_SETTING_PARAMS selectSettingParams;
URB urb;
NTSTATUS Status;
//
// Initialize the URB structure here.
//
...
//
// Initialize the WDF_USB_INTERFACE_SELECT_SETTING_PARAMS
// structure and call WdfUsbInterfaceSelectSetting.
//
WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB(
&selectSettingParams,
&urb
);
Status = WdfUsbInterfaceSelectSetting(
UsbInterface,
WDF_NO_OBJECT_ATTRIBUTES,
&selectSettingParams
);
