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