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.
