All this is windows specific, I have never seen this tag thing on other OS. > In other words, isn't a mmap ( without(!) tag ) always bound to a > "real" file in the file system ? No: mmap makes the link between a memory area and a file descriptor. Nothing force the file descriptor to be bound to a "real" file. POSIX defines shm_open to create shared memory file descriptor. AFAIK, this is the standard way to share memory between processes on modern unices: first create a memory area using shm_open, and then mmap it.
