The link http://docs.hp.com/en/B3782-90716/ch08s14.html says that
posix shared memory objects are implemented on hp-ux using the
underlying file system. Does this mean that the shared memory objects
are implemented as regular files in the underlying file system such as
vxfs?
If so, this is strictly not a memory object. POSIX specification for
shared memory
objects says that the name starts with '/' but no embedded '/' chars in
the name.
When I try this on hp-ux, it fails because it tries to create the
object in the root (/)
file system and the user has no permission to create a file in the root
file system.
On linux, the same thing works because it creates a 'file' in the tmpfs
file system
(not in the root file system).
How are POSIX shared memory objects implemented on hp-ux?
