```

## Parameters

- `allocator`: The allocator to use. Pass NULL or doc://com.apple.documentation/documentation/CoreFoundation/kCFAllocatorDefault to use the default allocator.
- `nodename`: The node name of the desired host. This name is the same as that passed to the gethostbyname or getaddrinfo functions. The value of this parameter is copied into the new object.
