.. hook:: H_SEND_NOTIFY_FAIL

  :arg string value: void <name>(string msg, object msgobj, object orig_cmd_giver)
  :arg closure value: void <closure>(string msg, object msgobj, object orig_cmd_giver)

  Optional hook to send the notify fail message, regardless of how it was determined, to the player. If the hook is not set, the message is delivered using :efun:`tell_object` internally. Hook setting can be a string or a closure.

  If the hook is a string, it is the name of a (possibly static) function to call in the current command giver. If the hook is a closure, it is the function to be called. Lambda closures are bound to the current command giver first.

  The arguments to the call are:
   - <msg> is the notify fail message to be delivered.
   - <msgobj> is the object which set the message. It is 0 for the default message.
   - <orig_cmd_giver> is the object for which the original command was first received. It is usually identical with the current command giver ``this_player()``.
