Constant jack::client_status::NAME_NOT_UNIQUE

pub const NAME_NOT_UNIQUE: ClientStatus = ClientStatus{bits: j::JackNameNotUnique,}

The desired client name was not unique. With the USE_EXACT_NAME option this situation is fatal. Otherwise, the name was modified by appending a dash and a two-digit number in the range "-01" to "-99". Client::name() will return the exact string that was used. If the specified client_name plus these extra characters would be too long, the open fails instead.
