31 .Nd report System V interprocess communication facilities status
44 program provides information on System V interprocess communication
45 (IPC) facilities on the system.
47 The options are as follows:
50 Show the maximum amount of information possible when
51 displaying active semaphores, message queues,
52 and shared memory segments.
53 (This is shorthand for specifying the
62 Show the maximum allowed sizes for active semaphores, message queues,
63 and shared memory segments.
65 .Dq maximum allowed size
66 is the maximum number of bytes in a message on a message queue,
67 the size of a shared memory segment,
68 or the number of semaphores in a set of semaphores.
70 Show the creator's name and group for active semaphores, message queues,
71 and shared memory segments.
73 Display information about active shared memory segments.
75 Show outstanding usage for active message queues,
76 and shared memory segments.
79 is the number of messages in a message queue, or the number
80 of processes attached to a shared memory segment.
82 Show the process ID information for active semaphores, message queues,
83 and shared memory segments.
85 .Dq process ID information
86 is the last process to send a message to or receive a message from
88 the process that created a semaphore, or the last process to attach
89 or detach a shared memory segment.
91 Display information about active message queues.
93 Display information about active semaphores.
95 Show access times for active semaphores, message queues,
96 and shared memory segments.
97 The access times is the time
98 of the last control operation on an IPC object,
99 the last send or receive of a message,
100 the last attach or detach of a shared memory segment,
101 or the last operation on a semaphore.
