What about adding the special character '+' to bb_opt_complementaly?
"+" A plus between two options, or between an option and a group
of options means that the options depend on each other. An
error will be forced if the options are not used together.
The start-stop-daemon applet has the options "-m" and "-p".
Both options (makepid and pidfile) have to be given. If one
of the options are missing, bb_getopt_ulflags's return value
will have the error flag set (BB_GETOPT_ERROR).
static char *pidfile = NULL;
static FILE *pidf = NULL;
bb_opt_complementaly = "m+p:p+m";
opt = bb_getopt_ulflags(argc, argv, "mp:", &pidfile);
if (opt & 1 && opt & 2) /* user wants _us_ to make the pidfile */
pidf = bb_xfopen(pidfile, "w");
What do you think?
