WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS function (wdfusb.h)
[Applies to KMDF and UMDF]
The WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS function initializes a WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure so that a driver can specify a configuration by using USB descriptors.
Syntax
void WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS(
[out] PWDF_USB_DEVICE_SELECT_CONFIG_PARAMS Params,
[in] PUSB_CONFIGURATION_DESCRIPTOR ConfigDescriptor,
[in] PUSB_INTERFACE_DESCRIPTOR *InterfaceDescriptors,
[in] ULONG NumInterfaceDescriptors
);
Parameters
[out] Params
A pointer to a driver-allocated WDF_USB_DEVICE_SELECT_CONFIG_PARAMS structure.
[in] ConfigDescriptor
A pointer to a USB_CONFIGURATION_DESCRIPTOR structure.
[in] InterfaceDescriptors
A pointer to an array of USB_INTERFACE_DESCRIPTOR structures.
[in] NumInterfaceDescriptors
The number of elements that is in the InterfaceDescriptors array.
Return value
None
Remarks
The WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS 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 WdfUsbTargetDeviceSelectConfigTypeInterfacesDescriptor.
This function uses the ConfigDescriptor, InterfaceDescriptors, and NumInterfaceDescriptors parameters to set the structure's Types.Descriptor union members.
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_MULTIPLE_INTERFACES
- WDF_USB_DEVICE_SELECT_CONFIG_PARAMS_INIT_INTERFACES_DESCRIPTORS
