IOUSBGetNextInterfaceDescriptor(_:_:)

Declaration

func IOUSBGetNextInterfaceDescriptor(_ configurationDescriptor: UnsafePointer<IOUSBConfigurationDescriptor>!, _ currentDescriptor: UnsafePointer<IOUSBDescriptorHeader>!) -> UnsafePointer<IOUSBInterfaceDescriptor>!

Parameters

• configurationDescriptor:

  A configuration descriptor that contains the descriptors to iterate through.

• currentDescriptor:

  A descriptor pointer within the bounds of configurationDescriptor, or nil.

Return Value

The next interface descriptor pointer, or nil if no matching descriptor returns.

Discussion
