WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB function
[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.
Syntax
VOID WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB( _Out_ PWDF_USB_INTERFACE_SELECT_SETTING_PARAMS Params, _In_ PURB Urb );
Parameters
- Params [out]
-
A pointer to a driver-allocated WDF_USB_INTERFACE_SELECT_SETTING_PARAMS structure.
- Urb [in]
-
A pointer to a URB structure.
Return value
None
Remarks
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:
-
WDF_USB_INTERFACE_SELECT_SETTING_PARAMS_INIT_URB
Examples
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
);
