Dialog Windows

  switch (result) {

Notes:

• Constants such as OKAY, YES, NO and CANCEL are returned from dialog windows which ask multiple choice questions.
• The string returned from ask_string should later be freed.
• All dialog windows accept a pointer to an App as their first parameter, and a window title string as the second parameter.
