_USBC_FUNCTION_DESCRIPTOR structure

Description

The USBC_FUNCTION_DESCRIPTOR structure describes a USB function and its associated interface collection.

Members

`FunctionNumber`

The zero-based index of the interface collection.

`NumberOfInterfaces`

The number of interfaces in the interface collection.

`InterfaceDescriptorList`

An array of pointers to USB_INTERFACE_DESCRIPTOR-type structures that describe the interfaces in the interface collection.

`HardwareId`

The hardware identifier of the interface collection.

`CompatibleId`

The compatible identifier of the interface collection.

`FunctionDescription`

A description of the interface collection in human-readable text.

`FunctionFlags`

Vendor-defined flags that describe the interface collection.

`Reserved`

Reserved.

Remarks

For information on how to use user-defined callback routines to provide a custom definition of the interface collections on a device, see Customizing Enumeration of Interface Collections for Composite Devices.
