# IOUSBGetNextDescriptorWithType

Finds the next descriptor matching a given type within a configuration descriptor.

```
const IOUSBDescriptorHeader *IOUSBGetNextDescriptorWithType(const IOUSBConfigurationDescriptor *configurationDescriptor, const IOUSBDescriptorHeader *currentDescriptor, const uint8_t type);
```

## Parameters

`configurationDescriptor`

The configuration descriptor that contains the descriptors to iterate through.

`currentDescriptor`

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

`type`

The type of descriptor to find.

## Return Value

A descriptor pointer, or `NULL` if no matching descriptor can be found.

## Discussion

This method uses `getNextDescriptor`, and further validates that the returned descriptor’s bDescriptorType field matches the type parameter.
