Hi Matthew,

https://man7.org/linux/man-pages/man3/shm_open.3.html says:For portable use, a shared memory object should be identified by a name of the form /somename; that is, a null-terminated string of up to NAME_MAX (i.e., 255) characters consisting of an initial slash, followed by one or more characters, none of which are slashes. Changing the shm_open call to shm_open("/123", O_CREAT | O_RDWR, 0666); returns 3 and sets errno to zero. Csaba
