IRCC, shm in that kernel is a filesystem and isn't accessed any more using
the System V functions. I'm not sure myself how you really do it because I
don't use that kernel (too lazy) but if you grep through documentation
looking for shm, it should list what you need to mount the fs and then
acccess it.

AFAIK, shm is not got using open,close, read and so on like a normal FD
but I could be well wrong there.

Most awkwardly, all old apps with shm will throw a fit which could be
irrating
