this box doesn't have any shared memory segments active (which isn't surprising as it's a headless build/dev box). here's the output, but i'm not sure it exactly answers your question ? if not, i'll have to slap together a few tests (maybe grab some from LTP). $ ./strace -eipc ipcs shmctl(0, IPC_64|SHM_INFO, 0) = 0 ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status shmctl(0, IPC_64|SHM_STAT, 0) = -1 EINVAL (Invalid argument) semctl(0, 0, IPC_64|SEM_INFO, 0x11f9bcfa0) = 0 ------ Semaphore Arrays -------- key semid owner perms nsems semctl(0, 0, IPC_64|SEM_STAT, 0x11f9bcfc8) = -1 EINVAL (Invalid argument) msgctl(0, IPC_64|MSG_INFO, 0) = 0 ------ Message Queues -------- key msqid owner perms used-bytes messages msgctl(0, IPC_64|MSG_STAT, 0) = -1 EINVAL (Invalid argument) +++ exited with 0 +++ -mike
