Hey, pludi:
memset() on the string pointed to by argv[1] works on osx 10.4.11, where modifying the pointer in argv[1] directly (as my code was doing) failed.
Incidentally, as an unprivileged user, copying the suid ps binary so that it is no longer suid seems to work fine. I only tested a few options, however, so it's possible there's a privileged code path that I did not visit, just waiting to blow things up, but if collecting the process info did not require privilege -- I took a brief peek at Apple's ps.c, and it's using sysctl to gather the info; so, not surprising that privilige is not required for that step -- I don't see what would.
Regards,
Alister
