       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 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.1‐2017, Section8.2, InternationalizationVariables 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.

       None.

       The following exit values shall be returned:

        0    Successful completion.

       >0    An error occurred.

       None.

       None.

       None.

       ipcrm — remove an XSI message queue, semaphore set, or shared memory segment identifier

       None.

       The ipcrm utility shall conform to the Base Definitions volume of  POSIX.1‐2017,  Section12.2,  UtilitySyntaxGuidelines.

       The following options shall be supported:

       -qmsgid  Remove  the  message  queue  identifier msgid from the system and destroy the message queue and
                 data structure associated with it.

       -mshmid  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.

       -ssemid  Remove  the  semaphore  identifier  semid from the system and destroy the set of semaphores and
                 data structure associated with it.

       -Qmsgkey Remove the message queue identifier, created with key msgkey, from the system and  destroy  the
                 message queue and data structure associated with it.

       -Mshmkey 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.

       -Ssemkey Remove the semaphore identifier, created with key semkey, from the system and destroy  the  set
                 of semaphores and data structure associated with it.

       None.
