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