# CFHostGetAddressing(_:_:)

Gets the addresses from a host.

## Declaration

```swift
func CFHostGetAddressing(_ theHost: CFHost, _ hasBeenResolved: UnsafeMutablePointer<DarwinBoolean>?) -> Unmanaged<CFArray>?
```

## Parameters

- `theHost`: The CFHost whose addresses are to be obtained. This value must not be NULL.
- `hasBeenResolved`: On return, a pointer to a Boolean that is TRUE if addresses were available and FALSE if addresses were not available. This parameter can be null.

## Discussion

Discussion This function gets the addresses from a CFHost. The CFHost must have been previously resolved. To resolve a CFHost, call CFHostStartInfoResolution(_:_:_:). Special Considerations This function gets the addresses in a thread-safe way, but the resulting data is not thread-safe. The data is returned as a “get” as opposed to a copy, so the data is not safe if the CFHost is altered from another thread.
