IPCRM(1P) POSIX Programmer's Manual IPCRM(1P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
ipcrm — remove an XSI message queue, semaphore set, or shared memory
segment identifier
ipcrm [−q msgid|−Q msgkey|−s semid|−S semkey|−m shmid|−M shmkey]...
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.
The ipcrm utility shall conform to the Base Definitions volume of
POSIX.1‐2008, 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.
None.
Not used.
None.
The following environment variables shall affect the execution of
ipcrm:
LANG Provide a default value for the internationalization
variables that are unset or null. (See the Base Definitions
volume of POSIX.1‐2008, Section 8.2, Internationalization
Variables for the precedence of internationalization
variables used to determine the values of locale
categories.)
LC_ALL If set to a non-empty string value, override the values of
all the other internationalization variables.
LC_CTYPE Determine the locale for the interpretation of sequences of
bytes of text data as characters (for example, single-byte
as opposed to multi-byte characters in arguments).
LC_MESSAGES
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to
standard error.
NLSPATH Determine the location of message catalogs for the
processing of LC_MESSAGES.
Default.
Not used.
The standard error shall be used only for diagnostic messages.
None.
None.
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Default.
The following sections are informative.
None.
None.
None.
None.
