.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program uses the
|
|
.Xr dialog 3
|
|
library to present a menu of available devices meeting some set of
|
|
criteria. The list of devices is obtained using the
|
|
.Xr sysctl 3
|
|
device configuration database
|
|
.Pq Dq devconf ,
|
|
and intersected with the list of
|
|
.No Ar name Ns s

|
|
flags are supported:
|
|
.Bl -tag -width mhmhelpfile
|
|
.It Fl c Ar class
|
|
specifies a class of devices to further restrict the available
|
|
choices. Multiple
|
|
.Fl c
|

|
|
classes is used. The following classes are currently supported:

at the beginning of a string requests the complement of the specified

requests devices with state
|
|
.Dv DC_UNKNOWN .
