I don't see why not. I get: lockfile(1) - conditional semaphore-file creator ipcrm(1) - remove the specified message queues, semaphore sets, and shared memory segments semctl(2) - control operations on a semaphore set semget(2) - obtain a semaphore id semop(2) - atomic array of operations on a semaphore set ...so, looks like upgrade time. -- Alan Batie ------ What goes up, must come down. batie@aahz.passedge.com \ / Ask any system administrator. +1 503-466-8407 (voice) \ / --unknown D0 D2 39 0E 02 34 D6 B4 \/ 5A 41 21 8F 23 5F 08 9D --h31gzZEtNLTqOjlF Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 5.0i for non-commercial use MessageID: noq3jYdV3PWTC43k7dPAev5e7I76rxbn iQCVAwUBOVjjEhCfrckvDwdpAQHXnwP+KlKQwwo6QIJfb+gpeoMpnJaqhEDjbGwV KUn7HefKqZVp4Doi+3EI3kVf4SAqNTo2vJ5C796MeSJfQZH6JgVbgqpmQXyMaGxz 5YDcV/rWf3Ztwwyp43JlgaG1E/o7CpFwzWTBiOkbcAaywTrOIN/Qys8FpuPUWGtN Mi1iQ/ch1Ss= =Cz1d -----END PGP SIGNATURE----- --h31gzZEtNLTqOjlF-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
