IPCMK(1)                      User Commands                     IPCMK(1)

NAME

       ipcmk - make various IPC resources

SYNOPSIS

       ipcmk [options]

DESCRIPTION

       ipcmk allows you to create System V inter-process communication
       (IPC) objects: shared memory segments, message queues, and
       semaphore arrays.

OPTIONS

       Resources can be specified with these options:

       -M, --shmem size
           Create a shared memory segment of size bytes. The size
           argument may be followed by the multiplicative suffixes KiB
           (=1024), MiB (=1024*1024), and so on for GiB, etc. (the "iB"
           is optional, e.g., "K" has the same meaning as "KiB") or the
           suffixes KB (=1000), MB (=1000*1000), and so on for GB, etc.

       -Q, --queue
           Create a message queue.

       -S, --semaphore number
           Create a semaphore array with number of elements.

       Other options are:

       -p, --mode mode
           Access permissions for the resource. Default is 0644.

       -h, --help
           Display help text and exit.

       -V, --version
           Print version and exit.
