tmux.ControlClient.NextNotification

NextNotification returns the next ordered control-mode notification. Exactly one caller may execute it at a time. Close releases the queue and makes subsequent reads report os.ErrClosed, drained through queued notifications first. Natural process exit before a caller asked to close instead reports ErrControlStreamLost - most often because the server the underlying tmux client was attached to exited - naming the tmux exit reason when one was sent. A terminal reader error follows notifications queued before that failure. A full bounded queue likewise drains before reporting ControlNotificationOverflowError .
