75 * @param basic_call The call to mkisofs. May contain tokens that will be resolved to actual data. The tokens are:
76 * - @c _ISO_ will become the ISO file (@p isofile)
77 * - @c _CD#_ becomes the CD number (@p cd_no)
78 * - @c _ERR_ becomes the logfile (@p g_logfile)
79 * @param isofile Replaces @c _ISO_ in @p basic_call. Should probably be the ISO image to create (-o parameter to mkisofs).
80 * @param cd_no Replaces @c _CD#_ in @p basic_call. Should probably be the CD number.
81 * @param logstub Unused.
82 * @param what_i_am_doing The action taking place (e.g. "Making ISO #1"). Used as the title of the progress dialog.
83 * @return Exit code of @c mkisofs (0 is success, anything else indicates failure).
84 * @bug @p logstub is unused.
