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;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:
$minor = new Solaris::DeviceTree::Libdevinfo::MinorNode($minor_data, $devinfo_node)
The constructor takes a SWIG-pointer to the C data structure of a minor node di_minor_t and a backreference to the Solaris::DeviceTree::Libdevinfo object which generates this instance.
$name = $minor->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'.
$path = $minor->devfs_path
Return the complete physical path including the minor node
($majnum,$minnum) = $minor->devt
Returns the major and minor device number as a pair for the node. The major numbers should be the same for all minor nodes return by a Solaris::DeviceTree::Libdevinfo node.
$type = $minor->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 = $minor->spectype
Returns the type of the minor node. Returns raw for a raw device block for a block device
if( $minor->is_raw_device ) { ... }
Returns true if the minor node is a raw device
if( $minor->is_block_device ) { ... }
Returns true if the minor node is a block device
$node = $minor->node
Returns the associated Solaris::DevinfoTree node. One Solaris::DevinfoTree node can have multiple minor nodes.
