## 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
           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
           Create a semaphore array with _number_ of elements.

       Other options are:

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