ipcmk - make various IPC resources
ipcmk allows you to create 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. -V, --version Display version information and exit. -h, --help Display help text and exit.
