Also, the claim "The API for /dev/shm is shm_open()" is incorrect. See the other message for the history. When something is in the file system, then by default the file system APIs (including creat, open, read, write, close, execve, dlopen, ...) are legitimate uses. (Originally [System V] shared memory was *not* in the file system, and this caused problems.)
Don't conflate SysV and POSIX shared memory. They are completely orthogonal. SysV shared memory does not appear in /dev/shm.
