  | Does it work for posix shmem and semaphore too?

     -m      Display information about active shared memory segments.

     -o      Show outstanding usage for active message queues, and shared
             memory segments.

     -p      Show the process ID information for active semaphores, message
             queues, and shared memory segments.

     -q      Display information about active message queues.

     -s      Display information about active semaphores.

     -t      Show access times for active semaphores, message queues, and
             shared memory segments.

     -M      Display system information about shared memory.

     -Q      Display system information about messages queues.

     -S      Display system information about semaphores.

     -T      Display system information about shared memory, message queues
             and semaphores.  (This is shorthand for specifying the -M, -Q,
             and -S options.)

The man pages are all on line - you could easily discover all of this
for yourself.
