29 /*----- Revision history --------------------------------------------------*
32 * Revision 1.4 1999/04/29 20:48:13 mdw
33 * Add documentation for `msg'.
35 * Revision 1.3 1999/03/25 23:36:10 mdw
36 * Compile to nothing in absence of GTK, for the benefit of parent packages
37 * which contain non-GTK-dependent parts.
39 * Revision 1.2 1998/12/15 23:48:06 mdw
40 * Use `dstr_putf' for formatting, rather than `sprintf'.
42 * Revision 1.1 1998/12/11 09:44:21 mdw

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