Is there a POSIX-y way to allocating shared memory that's not tied to a specific filename? I.e. memory that is shared between processes only by passing SCM_RIGHTS messages via UNIX domain sockets?

1Would the sequence shm_open(), mmap(), shm_unlink() help? Will it dispose of the file, but keep the memory allocated and associated file descriptors usable? – Martin Sustrik May 15 '13 at 09:03

Yes they are still valid file descriptors, you can use it. I was asking same question(anonymous POSIX shared memory). Guess POSIX only supports named shared memory. – Yakup Türkan May 12 '18 at 06:12

For Linux specific, one can use `MAP_ANONYMOUS`. – Ciro Santilli Путлер Капут 六四事 Aug 27 '18 at 13:59
