94 strings to prompt for data. The names are UI_{add,dup}_<function>_string
95 and UI_{add,dup}_input_boolean.
96
97 UI_{add,dup}_<function>_string have the following meanings:
98 add add a text or prompt string. The pointers given to these
99 functions are used verbatim, no copying is done.
100 dup make a copy of the text or prompt string, then add the copy
101 to the collection of strings in the user interface.
102 <function>
103 The function is a name for the functionality that the given
104 string shall be used for. It can be one of:
105 input use the string as data prompt.
106 verify use the string as verification prompt. This
107 is used to verify a previous input.
108 info use the string for informational output.
109 error use the string for error output.
110 Honestly, there's currently no difference between info and error for the
111 moment.
112
113 UI_{add,dup}_input_boolean have the same semantics for "add" and "dup",
114 and are typically used when one wants to prompt for a yes/no response.
115
116
117 All of the functions in this group take a UI and a prompt string.
118 The string input and verify addition functions also take a flag argument,
119 a buffer for the result to end up with, a minimum input size and a maximum
120 input size (the result buffer MUST be large enough to be able to contain
121 the maximum number of characters). Additionally, the verify addition
122 functions takes another buffer to compare the result against.
123 The boolean input functions take an action description string (which should
124 be safe to ignore if the expected user action is obvious, for example with
125 a dialog box with an OK button and a Cancel button), a string of acceptable
126 characters to mean OK and to mean Cancel. The two last strings are checked
127 to make sure they don't have common characters. Additionally, the same
128 flag argument as for the string input is taken, as well as a result buffer.
129 The result buffer is required to be at least one byte long. Depending on
130 the answer, the first character from the OK or the Cancel character strings
131 will be stored in the first byte of the result buffer. No NUL will be
132 added, so the result is *not* a string.
133
134 On success, the all return an index of the added information. That index
135 is usefull when retrieving results with UI_get0_result(). */

251/* ---------- For method writers ---------- */
252/* A method contains a number of functions that implement the low level
253 of the User Interface. The functions are:
254
255 an opener This function starts a session, maybe by opening
256 a channel to a tty, or by opening a window.
257 a writer This function is called to write a given string,
258 maybe to the tty, maybe as a field label in a
259 window.
260 a flusher This function is called to flush everything that
261 has been output so far. It can be used to actually
262 display a dialog box after it has been built.
263 a reader This function is called to read a given prompt,
264 maybe from the tty, maybe from a field in a
265 window. Note that it's called wth all string
266 structures, not only the prompt ones, so it must
267 check such things itself.
268 a closer This function closes the session, maybe by closing
269 the channel to the tty, or closing the window.
270
271 All these functions are expected to return:
272
273 0 on error.
274 1 on success.
275 -1 on out-of-band events, for example if some prompting has
276 been canceled (by pressing Ctrl-C, for example). This is
277 only checked when returned by the flusher or the reader.
278
279 The way this is used, the opener is first called, then the writer for all
280 strings, then the flusher, then the reader for all strings and finally the
281 closer. Note that if you want to prompt from a terminal or other command
282 line interface, the best is to have the reader also write the prompts
283 instead of having the writer do it. If you want to prompt from a dialog
284 box, the writer can be used to build up the contents of the box, and the
285 flusher to actually display the box and run the event loop until all data
286 has been given, after which the reader only grabs the given data and puts
287 them back into the UI strings.
288
289 All method functions take a UI as argument. Additionally, the writer and
290 the reader take a UI_STRING.
