Usually it is the reverse: to treat a file as an chunk of memory.
In more OSes more advanced than Linux one can have shared memory without
any files involved. The memory object could even be anonymous if one
process passes a handle to the memory to another.
Linux has special sockets for passing file descriptors, but all is quite
purposeless because shared memory still requires a file behind it.
