# IOUSBGetNextEndpointDescriptor

Finds the next endpoint descriptor associated with an interface descriptor.

## Declaration

```occ
const IOUSBEndpointDescriptor *IOUSBGetNextEndpointDescriptor(const IOUSBConfigurationDescriptor *configurationDescriptor, const IOUSBInterfaceDescriptor *interfaceDescriptor, const IOUSBDescriptorHeader *currentDescriptor);
```

## Parameters

- `configurationDescriptor`: A configuration descriptor that contains the descriptors to iterate through.
- `interfaceDescriptor`: An interface descriptor within the bounds of the configuration descriptor.
- `currentDescriptor`: A descriptor pointer within the bounds of the configuration descriptor, or NULL.

## Return Value

Return Value An endpoint descriptor pointer, or NULL if no matching descriptor can be found.

## Discussion

Discussion This method uses getNextAssociatedDescriptorWithType to fetch the next endpoint descriptor associated with a specific interface descriptor.
