Shared memory is a form of Interprocess Communication (IPC). It allows memory regions of one process to be shared with another process. A simple way to achieve this is to mmap(2) an anonymous memory region and fork(), this memory is now shared between the parent and child. Unassociated processes can also do shared memory. There is two common methods for this SYSV shared memory or POSIX shared memory.
