- The iippccss program provides information on System V interprocess communica-
- tion (IPC) facilities on the system.
-
- The options are as follows:
-
- --aa Show the maximum amount of information possible when displaying
- active semaphores, message queues, and shared memory segments.
- (This is shorthand for specifying the --bb, --cc, --oo, --pp, and --tt op-
- tions.)
-
- --bb Show the maximum allowed sizes for active semaphores, message
- queues, and shared memory segments. The ``maximum allowed size''
- is the maximum number of bytes in a message on a message queue,
- the size of a shared memory segment, or the number number of
- semaphores in a set of semaphores.
-
- --cc Show the creator's name and group for active semaphores, message
- queues, and shared memory segments.
-
- --mm Display information about active shared memory segments.
-
- --oo Show outstanding usage for active message queues, and shared mem-
- ory segments. The ``outstanding usage'' is the number of mes-
- sages in a message queue, or the number of processes attached to
- a shared memory segment.
-
- --pp Show the process ID information for active semaphores, message
- queues, and shared memory segments. The ``process ID
- information'' is the last process to send a message to or receive
- a message from a message queue, the process that created a
- semaphore, or the last process to attach or detach a shared memo-
- ry segment.
-
- --qq Display information about active message queues.
-
- --ss Display information about active semaphores.
-
- --tt Show access times for active semaphores, message queues, and
- shared memory segments. The access times is the time of the last
- control operation on an IPC object, the last send or receive of a
- message, the last attach or detach of a shared memory segment, or
- the last operation on a semaphore.
-
- --CC _s_y_s_t_e_m
- Extract the name list from the specified system instead of the
- default ``_/_n_e_t_b_s_d''.
-
- --MM Display system information about shared memory.
-
- --NN _c_o_r_e
- Extract values associated with the name list from the specified
- core instead of the default ``_/_d_e_v_/_k_m_e_m''. and semaphores.
-
-
-
- --QQ Display system information about messages queues.
-
- --SS Display system information about semaphores.
-
- --TT Display system information about shared memory, message queues
-
- If none of the --MM, --mm, --QQ, --qq, --SS, or --ss options are specified, informa-
- tion about all active IPC facilities is listed.

- System data structures may change while iippccss is running; the output of
- iippccss is not guaranteed to be consistent.
-
- BBUUGGSS
- This manual page is woefully incomplete, because it does not at all at-
- tempt to explain the information printed by iippccss.
