NAME
Solaris::DeviceTree::Libdevinfo::MinorNode - Minor node of the Solaris devicetree
SYNOPSIS
use Solaris::DeviceTree::Libdevinfo;
$tree = new Solaris::DeviceTree::Libdevinfo;
@disks = $tree->find_nodes( type => 'disk' );
@minor = @disks->minor_nodes;
$name = $minor->name
$path = $minor->devfs_path
($majnum,$minnum) = $minor->devt
$type = $minor->nodetype
$spectype = $minor->spectype
if( $minor->is_raw_device ) { ... }
if( $minor->is_block_device ) { ... }
$treenode = $minor->node
DESCRIPTION
This class implements a minor node in the libdevinfo devicetree. This is an internal class to Solaris::DeviceTree::Libdevinfo
. There should be no need to generate instances of this class in an application explicitly. Instances are generated only from Solaris::DeviceTree::Libdevinfo::minor_nodes().
METHODS
The following methods are available:
name
Return the name of the minor node. This is used e.g. as suffix of the device filename. For disks this is something like ':a' or ':a,raw'.
devfs_path
Return the complete physical path including the minor node
devt
Returns the major and minor device number as a list for the node. The major numbers should be the same for all minor nodes returned by a Solaris::DeviceTree::Libdevinfo node.
nodetype
Returns the nodetype of the minor node. Legal return values can be taken from <sys/sunddi.h>
. With this call you can differentiate between pseudo nodes, displays and stuff.
spectype
Returns the type of the minor node. Returns raw for a raw device block for a block device
is_raw_device
Returns true if the minor node is a raw device.
is_block_device
Returns true if the minor node is a block device.
node
Returns the associated Solaris::DevinfoTree::Libdevinfo node. One treenode can (and usually does) have multiple minor nodes.
