displays the I/O Kit registry. It
shows the hierarchical registry structure as an inverted tree. The
provider-client relationships among those objects is shown as follows:
+-o provider
|
+-o client
By default, object properties are not shown. The use of the
-c
, -k
,
-l
, or -n
options cause
ioreg
to show properties for objects that match the
specified criteria.
By supplying the -r
option, the user may
specify the object which will appear at the root of the tree with the
-c
, -k
, or
-n
options. If root matches more than one object,
multiple trees will be displayed.
The options are as follows:
-a
-b
-c
-d
ioreg
to display only (sub)tree root nodes; children will not be shown.-f
