[dbus/unique-name $conn]

## Parameters - `$conn` — connection from `dbus/connect` `dbus/connect` performs HELLO synchronously, so the name is normally available as soon as connect returns. ## Examples

[dbus/unique-name $conn]     # → ":1.0"

## Returns String unique name, `nil` when not yet known, or `%Err{:message}` when the argument is not a dbus connection. ## See Also `dbus/connect`, `dbus/register-name`, `dbus/info`
