A call to SetupDiEnumDeviceInterfaces retrieves a pointer to a structure that identifies a specific device interface in the previously retrieved DeviceInfoSet array. The call specifies a device interface by passing an array index. To retrieve information about all of the device interfaces, an application can loop through the array, incrementing the array index until the function returns zero, indicating that there are no more interfaces. The GetLastError API function then returns No more data is available.
