# hv_gic_config_set_distributor_base(_:_:)

Sets the generic interrupt controller (GIC) distributor region’s base address.

## Declaration

```swift
func hv_gic_config_set_distributor_base(_ config: hv_gic_config_t, _ distributor_base_address: hv_ipa_t) -> hv_return_t
```

## Parameters

- `config`: The GIC configuration object.
- `distributor_base_address`: The guest’s physical address for the distributor.

## Return Value

Return Value A new GIC configuration object.

## Discussion

Discussion Guest physical address for the distributor base aligned to the byte value returned by hv_gic_get_distributor_base_alignment(_:). Release this object with os_release when it’s no longer needed.
