ipcmk - make various IPC resources

ipcmk [options]

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

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.
