 ### Handle send message errors

 * ```$res```: temporary variable containing the full transmission result, may be overwritten by any bashbot function.
 
 By default you don't have to care about retry, as bashbot resend the message after the requested time automatically.
 Only if the retry fails also an error is returned. The downside is that send_message functions will wait until resend is done.
