10

DESCRIPTION

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

OPTIONS

16       Resources can be specified with these options:
17
18       -M, --shmem size
19           Create a shared memory segment of size bytes. The size argument may
20           be followed by the multiplicative suffixes KiB (=1024), MiB
21           (=1024*1024), and so on for GiB, etc. (the "iB" is optional, e.g.,
22           "K" has the same meaning as "KiB") or the suffixes KB (=1000), MB
23           (=1000*1000), and so on for GB, etc.
24
25       -Q, --queue
26           Create a message queue.
27
28       -S, --semaphore number
29           Create a semaphore array with number of elements.
30
31       Other options are:
32
33       -p, --mode mode
34           Access permissions for the resource. Default is 0644.
35
36       -h, --help
37           Display help text and exit.
