/* 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 with, 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 all return an index of the added information. That index
is usefull 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 wth 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.
