84 * Arguments: @char *buttons@ = the button strings to display
85 * @char *msg@ = the message skeleton string
87 * Returns: Index of the button selected.
89 * Use: Displays a message to the user in a nice dialogue box and
90 * returns the index of the button selected.
92 * The @msg@ argument is a @printf@-style format string, which
93 * contains the message to actually be shown. The @buttons@
94 * argument is a comma-separated list of buttons to be drawn,
95 * from right to left. A button name can be preceded with `:'
96 * to indicate that it's the default, or `~' if it's the
97 * `cancel' button. The return value is the zero-based index
98 * of the button selected.
