WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG function (wdfusb.h)
[Applies to KMDF and UMDF]
The WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG function initializes a WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure so that a driver can deconfigure a USB device.
Syntax
void WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG(
[out] PWDF_USB_DEVICE_SELECT_CONFIG_PARAMS Params
);
Parameters
[out] Params
A pointer to a driver-allocated WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure.
Return value
None
Remarks
The WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG function zeros the WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure and sets the Size member to the size of the structure. It also sets the Type member to WdfUsbTargetDeviceSelectConfigTypeDeconfig.
To initialize a WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure, the driver must call one of the following functions:
- WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG
-
WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_MULTIPLE_INTERFACES
-
WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS
Examples
The following code example initializes a WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure and then calls WdfUsbTargetDeviceSelectConfig to deconfigure a device.
WDF_USB_DEVICE_SELECT_CONFIG_PARAMS configParams;
NTSTATUS status;
WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_DECONFIG(&configParams);
Status = WdfUsbTargetDeviceSelectConfig(
UsbDevice,
WDF_NO_OBJECT_ATTRIBUTES,
&configParams
);
