    NAME

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

    SYNOPSIS

    ipcrm [ -q msgid | -Q msgkey | -s semid | -S semkey |
           -m shmid | -M shmkey
    ] ...  

    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 privilege shall be allowed to remove an interprocess communication facility that was not created by or owned by the user invoking ipcrm.  

    OPTIONS

    The ipcrm facility supports the Base Definitions volume of IEEE Std 1003.1-2001, 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.

     

    OPERANDS

    None.  

    STDIN

    Not used.  

    INPUT FILES

    None.  

    ENVIRONMENT VARIABLES

    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 IEEE Std 1003.1-2001, 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 .

     

    ASYNCHRONOUS EVENTS

    Default.  

    STDOUT

    Not used.  

    STDERR

    The standard error shall be used only for diagnostic messages.  

    OUTPUT FILES

    None.  

    EXTENDED DESCRIPTION

    None.  

    EXIT STATUS

    The following exit values shall be returned:

     0
    Successful completion.
    >0
    An error occurred.

     

    CONSEQUENCES OF ERRORS

    Default.

    The following sections are informative.  

    APPLICATION USAGE

    None.  

    EXAMPLES

    None.  

    RATIONALE

    None.  

    FUTURE DIRECTIONS

    None.
