# IOUSBGetNextInterfaceAssociationDescriptor

Finds the next interface association descriptor in a configuration descriptor.

```
const IOUSBInterfaceAssociationDescriptor *IOUSBGetNextInterfaceAssociationDescriptor(const IOUSBConfigurationDescriptor *configurationDescriptor, const IOUSBDescriptorHeader *currentDescriptor);
```

## Parameters

`configurationDescriptor`

A configuration descriptor that contains the descriptors to iterate through.

`currentDescriptor`

A descriptor pointer within the bounds of the configuration descriptor, or `NULL`.

## Return Value

An interface association descriptor pointer, or `NULL` if no matching descriptor can be found.

## Discussion

This method uses `getNextDescriptorWithType` to fetch the next interface association descriptor.
