-   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 useful when retrieving results with UI_get0_result(). */

-/*-
-   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 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.  Additionally, the writer and
-   the reader take a UI_STRING.

+   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 useful when retrieving results with UI_get0_result(). */

+/*-

+   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 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.  Additionally, the writer and

+   the reader take a UI_STRING.
