Имя (Name)
ipcrm — remove an XSI message queue, semaphore set, or shared
memory segment identifier
Синопсис (Synopsis)
ipcrm [-q msgid|-Q msgkey|-s semid|-S semkey|-m shmid|-M shmkey]...
Описание (Description)
The ipcrm utility shall remove zero or more message queues,
semaphore sets, or shared memory segments. The interprocess
communication facilities to be removed are specified by the
options.
Only a user with appropriate privileges shall be allowed to
remove an interprocess communication facility that was not
created by or owned by the user invoking ipcrm.
Параметры (Options)
The ipcrm utility shall conform to the Base Definitions volume of
POSIX.1‐2017, Section 12.2, Utility Syntax Guidelines.
The following options shall be supported:
-q msgid Remove the message queue identifier msgid from the
system and destroy the message queue and data structure
associated with it.
-m shmid Remove the shared memory identifier shmid from the
system. The shared memory segment and data structure
associated with it shall be destroyed after the last
detach.
-s semid Remove the semaphore identifier semid from the system
and destroy the set of semaphores and data structure
associated with it.
-Q msgkey Remove the message queue identifier, created with key
msgkey, from the system and destroy the message queue
and data structure associated with it.
-M shmkey Remove the shared memory identifier, created with key
shmkey, from the system. The shared memory segment and
data structure associated with it shall be destroyed
after the last detach.
-S semkey Remove the semaphore identifier, created with key
semkey, from the system and destroy the set of
semaphores and data structure associated with it.
