- * The following functions are used to add strings to be printed and prompt
- * strings to prompt for data.  The names are UI_{add,dup}_<function>_string
- * and UI_{add,dup}_input_boolean.
- *
- * UI_{add,dup}_<function>_string have the following meanings:
- *      add     add a text or prompt string.  The pointers given to these
- *              functions are used verbatim, no copying is done.
- *      dup     make a copy of the text or prompt string, then add the copy
- *              to the collection of strings in the user interface.
- *      <function>
- *              The function is a name for the functionality that the given
- *              string shall be used for.  It can be one of:
- *                      input   use the string as data prompt.
- *                      verify  use the string as verification prompt.  This
- *                              is used to verify a previous input.
- *                      info    use the string for informational output.
- *                      error   use the string for error output.
- * Honestly, there's currently no difference between info and error for the
- * moment.
- *
- * UI_{add,dup}_input_boolean have the same semantics for "add" and "dup",
- * and are typically used when one wants to prompt for a yes/no response.
- *
- * All of the functions in this group take a UI and a prompt string.
- * The string input and verify addition functions also take a flag argument,
- * a buffer for the result to end up in, a minimum input size and a maximum
- * input size (the result buffer MUST be large enough to be able to contain
- * the maximum number of characters).  Additionally, the verify addition
- * functions takes another buffer to compare the result against.
- * The boolean input functions take an action description string (which should
- * be safe to ignore if the expected user action is obvious, for example with
- * a dialog box with an OK button and a Cancel button), a string of acceptable
- * characters to mean OK and to mean Cancel.  The two last strings are checked
- * to make sure they don't have common characters.  Additionally, the same
- * flag argument as for the string input is taken, as well as a result buffer.
- * The result buffer is required to be at least one byte long.  Depending on
- * the answer, the first character from the OK or the Cancel character strings
- * will be stored in the first byte of the result buffer.  No NUL will be
- * added, so the result is *not* a string.
- *
- * On success, the functions all return an index of the added information.
- * That index is useful when retrieving results with UI_get0_result().

- * ---------- For method writers ----------
- * A method contains a number of functions that implement the low level
- * of the User Interface.  The functions are:
- *
- *      an opener       This function starts a session, maybe by opening
- *                      a channel to a tty, or by opening a window.
- *      a writer        This function is called to write a given string,
- *                      maybe to the tty, maybe as a field label in a
- *                      window.
- *      a flusher       This function is called to flush everything that
- *                      has been output so far.  It can be used to actually
- *                      display a dialog box after it has been built.
- *      a reader        This function is called to read a given prompt,
- *                      maybe from the tty, maybe from a field in a
- *                      window.  Note that it's called with all string
- *                      structures, not only the prompt ones, so it must
- *                      check such things itself.
- *      a closer        This function closes the session, maybe by closing
- *                      the channel to the tty, or closing the window.
- *
- * All these functions are expected to return:
- *
- *       0      on error.
- *       1      on success.
- *      -1      on out-of-band events, for example if some prompting has
- *              been canceled (by pressing Ctrl-C, for example).  This is
- *              only checked when returned by the flusher or the reader.
- *
- * The way this is used, the opener is first called, then the writer for all
- * strings, then the flusher, then the reader for all strings and finally the
- * closer.  Note that if you want to prompt from a terminal or other command
- * line interface, the best is to have the reader also write the prompts
- * instead of having the writer do it.  If you want to prompt from a dialog
- * box, the writer can be used to build up the contents of the box, and the
- * flusher to actually display the box and run the event loop until all data
- * has been given, after which the reader only grabs the given data and puts
- * them back into the UI strings.
- *
- * All method functions take a UI as argument.  Additionally, the writer and
- * the reader take a UI_STRING.
