|
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 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 M
|
||||||
|
Display system information about shared memory.
|
||||||
|
.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
|
||||||
|
and semaphores.
|
||||||
|
(This is shorthand for specifying the
|
||||||
|
.Fl M ,
|
||||||
|
.Fl Q ,
|
||||||
|
and
|
||||||
|
.Fl S
|
||||||
|
options.)
|
||||||
|
.El
|
||||||
|
.Pp
|

If none of the
|
||||||
|
.Fl M ,
|

.Fl S ,
|
||||||
|
.Fl s ,
|
||||||
|
or
|

|
.Fl T
|
||||||
|
options are specified, information about all active IPC facilities is
|
