83 * @param cd_no Replaces @c _CD#_ in @p basic_call. Should probably be the CD number.
84 * @param logstub Unused.
85 * @param what_i_am_doing The action taking place (e.g. "Making ISO #1"). Used as the title of the progress dialog.
86 * @return Exit code of @c mkisofs (0 is success, anything else indicates failure).
