## Detailed Description

full implemented class for user_interaction based on callback functions.

this class is an inherited class of user_interaction it is used by dar command line programs, but you can use it if you wish.

## Constructor & Destructor Documentation

## user_interaction_callback()

libdar::user_interaction_callback::user_interaction_callback | ( | message_callback | x_message_callback,
|  | pause_callback | x_answer_callback,
|  | get_string_callback | x_string_callback,
|  | get_secu_string_callback | x_secu_string_callback,
|  | void * | context_value )

constructor which receive the callback functions.

Parameters

  [in] | x_message_callback | is used by message() method
  [in] | x_answer_callback | is used by the pause() method
  [in] | x_string_callback | is used by get_string() method
  [in] | x_secu_string_callback | is used by get_secu_string() method
  [in] | context_value | will be passed as last argument of callbacks when called from this object.

Note
  The context argument of each callback is set with the context_value given in the user_interaction_callback object constructor. The value can can be any arbitrary value (nullptr is valid), and can be used as you wish. Note that the listing callback is not defined here, but thanks to a specific method
