Export getopt (VUtibKJCt1o) and getopt_long (8VVXJxB5nlk) from libSceLibcInternal together with the guest variables optind (zCnSJWp-Qj8), optarg (zG0BNJOZdm4), opterr (yaFXXViLWPw), optopt (FwzVaZ8Vnus) and optreset (CZNm+oNmB-I). The NIDs were computed with tools/nid_names.py and all seven are in aerolib; the PS5 payload SDK f5d40f02 lists the functions and the five objects in sce_stubs/libSceLibcInternal.c. Titles (predicted stops from registry order, not observed runs): - XPSemu PPSA97358, after execv/execve, the signal waits, the credential setters, mlockall and tcsendbreak: "FAIL: unresolved ELF import VUtibKJCt1o from libSceLibcInternal.prx" (getopt idx 204, 10 call sites from 0xF6C23D), then optind (207), optreset (208), optarg (209). - RetroArch PPSA99169: getopt_long (idx 554, call sites 0xD2FC0C, 0xD3002A), optind (553), optarg (555). Behaviour follows FreeBSD release/11.4.0 8c639945: getopt is lib/libc/stdlib/getopt.c (no permutation, GNU "::" optional argument, lone "-" as an option when listed), getopt_long is getopt_internal from lib/libc/stdlib/getopt_long.c with GNU_COMPATIBLE (permutation, POSIXLY_CORRECT read through the guest getenv on the first call and on optreset, "+" and "-" prefixes, "W;", optind 0 as a reset, abbreviation and ambiguity rules and the GNU warning texts). Warnings are written to the guest stderr stream as "<__progname>: <message>", as warnx does. The struct option layout and argument kinds are include/getopt.h. The code lives in libSceLibcInternal because __progname is a libkernel export that libc cannot link. A null getopt option string, a null argument vector or argument, a negative optind and an optind moved inside a pending permutation throw where FreeBSD faults. getopt_long_only is not exported. guest_getopt runs the FreeBSD getopt_test cases (contrib/netbsd-tests t_getopt.sh with the h_getopt and h_getopt_long result format) plus grouped and optional arguments, "--", permutation order, "+" and "-" prefixes, optreset and optind 0 restarts, POSIXLY_CORRECT, all three long argument kinds, abbreviations, ambiguity, flag pointers, "W;", optopt with opterr 0 and the exact stderr text.
