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

245/* ---------- For method writers ---------- */
246/* A method contains a number of functions that implement the low level
247 of the User Interface. The functions are:
248
249 an opener This function starts a session, maybe by opening
250 a channel to a tty, or by opening a window.
251 a writer This function is called to write a given string,
252 maybe to the tty, maybe as a field label in a
253 window.
254 a flusher This function is called to flush everything that
255 has been output so far. It can be used to actually
256 display a dialog box after it has been built.
257 a reader This function is called to read a given prompt,
258 maybe from the tty, maybe from a field in a
259 window. Note that it's called wth all string
260 structures, not only the prompt ones, so it must
261 check such things itself.
262 a closer This function closes the session, maybe by closing
263 the channel to the tty, or closing the window.
264
265 All these functions are expected to return:
266
267 0 on error.
268 1 on success.
269 -1 on out-of-band events, for example if some prompting has
270 been canceled (by pressing Ctrl-C, for example). This is
271 only checked when returned by the flusher or the reader.
272
273 The way this is used, the opener is first called, then the writer for all
274 strings, then the flusher, then the reader for all strings and finally the
275 closer. Note that if you want to prompt from a terminal or other command
276 line interface, the best is to have the reader also write the prompts
277 instead of having the writer do it. If you want to prompt from a dialog
278 box, the writer can be used to build up the contents of the box, and the
279 flusher to actually display the box and run the event loop until all data
280 has been given, after which the reader only grabs the given data and puts
281 them back into the UI strings.
282
283 All method functions take a UI as argument. Additionally, the writer and
284 the reader take a UI_STRING.
