DESCRIPTION


ipcrm removes one or more messages, semaphores, or shared memory
identifiers.

OPTIONS


The following option is supported:

-z zone
Keys specified by other options refer to facilities in the

Removes the message queue identifier msqid from the system
and destroys the message queue and data structure associated
with it.


-s semid
Removes the semaphore identifier semid from the system and
destroys the set of semaphores and data structure associated
with it.


-M shmkey
Removes the shared memory identifier, created with key
shmkey, from the system. The shared memory segment and data
structure associated with it are destroyed after the last
detach.


-Q msgkey
Removes the message queue identifier, created with key
msgkey, from the system and destroys the message queue and
data structure associated with it.


-S semkey
Removes the semaphore identifier, created with key semkey,
from the system and destroys the set of semaphores and data
structure associated with it.


The details of the removes are described in msgctl(2), shmctl(2), and
