90 * The following functions are used to add strings to be printed and prompt
91 * strings to prompt for data. The names are UI_{add,dup}_<function>_string
92 * and UI_{add,dup}_input_boolean.
93 *
94 * UI_{add,dup}_<function>_string have the following meanings:
95 * add add a text or prompt string. The pointers given to these
96 * functions are used verbatim, no copying is done.
97 * dup make a copy of the text or prompt string, then add the copy
98 * to the collection of strings in the user interface.
99 * <function>
100 * The function is a name for the functionality that the given
101 * string shall be used for. It can be one of:
102 * input use the string as data prompt.
103 * verify use the string as verification prompt. This
104 * is used to verify a previous input.
105 * info use the string for informational output.
106 * error use the string for error output.
107 * Honestly, there's currently no difference between info and error for the
108 * moment.
109 *
110 * UI_{add,dup}_input_boolean have the same semantics for "add" and "dup",
111 * and are typically used when one wants to prompt for a yes/no response.
112 *
113 * All of the functions in this group take a UI and a prompt string.
114 * The string input and verify addition functions also take a flag argument,
115 * a buffer for the result to end up in, a minimum input size and a maximum
116 * input size (the result buffer MUST be large enough to be able to contain
117 * the maximum number of characters). Additionally, the verify addition
118 * functions takes another buffer to compare the result against.
119 * The boolean input functions take an action description string (which should
120 * be safe to ignore if the expected user action is obvious, for example with
121 * a dialog box with an OK button and a Cancel button), a string of acceptable
122 * characters to mean OK and to mean Cancel. The two last strings are checked
123 * to make sure they don't have common characters. Additionally, the same
124 * flag argument as for the string input is taken, as well as a result buffer.
125 * The result buffer is required to be at least one byte long. Depending on
126 * the answer, the first character from the OK or the Cancel character strings
127 * will be stored in the first byte of the result buffer. No NUL will be
128 * added, so the result is *not* a string.
129 *
130 * On success, the functions all return an index of the added information.
131 * That index is useful when retrieving results with UI_get0_result().

261 * ---------- For method writers ----------
262 * A method contains a number of functions that implement the low level
263 * of the User Interface. The functions are:
264 *
265 * an opener This function starts a session, maybe by opening
266 * a channel to a tty, or by opening a window.
267 * a writer This function is called to write a given string,
268 * maybe to the tty, maybe as a field label in a
269 * window.
270 * a flusher This function is called to flush everything that
271 * has been output so far. It can be used to actually
272 * display a dialog box after it has been built.
273 * a reader This function is called to read a given prompt,
274 * maybe from the tty, maybe from a field in a
275 * window. Note that it's called with all string
276 * structures, not only the prompt ones, so it must
277 * check such things itself.
278 * a closer This function closes the session, maybe by closing
279 * the channel to the tty, or closing the window.
280 *
281 * All these functions are expected to return:
282 *
283 * 0 on error.
284 * 1 on success.
285 * -1 on out-of-band events, for example if some prompting has
286 * been canceled (by pressing Ctrl-C, for example). This is
287 * only checked when returned by the flusher or the reader.
288 *
289 * The way this is used, the opener is first called, then the writer for all
290 * strings, then the flusher, then the reader for all strings and finally the
291 * closer. Note that if you want to prompt from a terminal or other command
292 * line interface, the best is to have the reader also write the prompts
293 * instead of having the writer do it. If you want to prompt from a dialog
294 * box, the writer can be used to build up the contents of the box, and the
295 * flusher to actually display the box and run the event loop until all data
296 * has been given, after which the reader only grabs the given data and puts
297 * them back into the UI strings.
298 *
299 * All method functions take a UI as argument. Additionally, the writer and
300 * the reader take a UI_STRING.
