55 * Arguments: @const char *title@ = the title for the message box
56 * @const char *buttons@ = the button strings to display
57 * @const char *msg@ = the message skeleton string
59 * Returns: Index of the button selected.
61 * Use: Displays a message to the user in a nice dialogue box and

64 * The @msg@ argument is a @printf@-style format string, which
65 * contains the message to actually be shown. The @buttons@
66 * argument is a comma-separated list of buttons to be drawn,
67 * from right to left. A button name can be preceded with `:'
68 * to indicate that it's the default, or `~' if it's the
69 * `cancel' button. The return value is the zero-based index
70 * of the button selected.
