Only usually, not "in practice". You can usefully call shm_open() with flags obtained from a variable. > MFC after: 3 days > Modified: head/lib/libc/sys/shm_open.2 > ============================================================================== > --- head/lib/libc/sys/shm_open.2 Fri Jan 29 10:20:11 2010 (r203160) > +++ head/lib/libc/sys/shm_open.2 Fri Jan 29 10:32:01 2010 (r203161) > @@ -39,6 +39,7 @@ > .Sh SYNOPSIS > .In sys/types.h > .In sys/mman.h > +.In fcntl.h > .Ft int > .Fn shm_open "const char *path" "int flags" "mode_t mode" > .Ft int This detail belongs in the description, not in the synopsis. This is correctly handled in POSIX. POSIX also correctly specifies the include of <sys/types.h> -- it wasn't specified for shm_open() even in POSIX.1-1996 though it was specified for some other functions then. Now it isn't specified for any functions. Bruce
