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 all return an index of the added information.

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.
