|

|
||||
.Nm ipcs
|
||||
.Op Fl abcmopqstMQST
|
||||
.Op Fl C Ar system
|
||||
.Op Fl N Ar core
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm ipcs
|
||||
program provides information on System V interprocess communication
|
||||
(IPC) facilities on the system.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl a
|
||||
Show the maximum amount of information possible when
|
||||
displaying active semaphores, message queues,
|
||||
and shared memory segments.
|
||||
(This is shorthand for specifying the
|
||||
.Fl b ,
|
||||
.Fl c ,
|
||||
.Fl o ,
|
||||
.Fl p ,
|
||||
and
|
||||
.Fl t
|
||||
options.)
|
||||
.It Fl b
|
||||
Show the maximum allowed sizes for active semaphores, message queues,
|
||||
and shared memory segments. The
|
||||
.Dq 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.
|
||||
.It Fl c
|
||||
Show the creator's name and group for active semaphores, message queues,
|
||||
and shared memory segments.
|
||||
.It Fl m
|
||||
Display information about active shared memory segments.
|
||||
.It Fl o
|
||||
Show outstanding usage for active message queues,
|
||||
and shared memory segments. The
|
||||
.Dq outstanding usage
|
||||
is the number of messages in a message queue, or the number
|
||||
of processes attached to a shared memory segment.
|
||||
.It Fl p
|
||||
Show the process ID information for active semaphores, message queues,
|
||||
and shared memory segments. The
|
||||
.Dq 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 memory segment.
|
||||
.It Fl q
|
||||
Display information about active message queues.
|
||||
.It Fl s
|
||||
Display information about active semaphores.
|
||||
.It Fl t
|
||||
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.
|
||||
.It Fl C Ar system
|
||||
Extract the name list from the specified system instead of the
|
||||
default
|
||||
.Dq Pa /kernel .
|
||||
.It Fl M
|
||||
Display system information about shared memory.
|
||||
.It Fl N Ar core
|
||||
Extract values associated with the name list from the specified
|
||||
core instead of the default
|
||||
.Dq Pa /dev/kmem .
|
||||
and semaphores.
|
||||
.It Fl Q
|
||||
Display system information about messages queues.
|
||||
.It Fl S
|
||||
Display system information about semaphores.
|
||||
.It Fl T
|
||||
Display system information about shared memory, message queues
|
||||
.El
|
||||
.Pp
|
||||
If none of the
|
||||
.Fl M ,
|
||||
.Fl m ,
|
||||
.Fl Q ,
|
||||
.Fl q ,
|
||||
.Fl S ,
|
||||
or
|
||||
.Fl s
|
||||
options are specified, information about all active IPC facilities is
|
||||
listed.
|
||||
.Sh RESTRICTIONS
|
||||
System data structures may change while
|
||||
.Nm ipcs
|
||||
is running; the output of
|
||||
.Nm ipcs
|
||||
is not guaranteed to be consistent.
|
||||
.Sh BUGS
|
||||
This manual page is woefully incomplete, because it does not
|
||||
at all attempt to explain the information printed by
|
||||
