NAME

Solaris::DeviceTree::OBP - Manipulation of OBP pathes

SYNOPSIS

use Solaris::DeviceTree::OBP( :DEFAULT );
my $tree = new Solaris::DeviceTree;
$bootpath = $tree->find_prop( devfs_path => '/chosen', prom_prop_name => 'bootpath' );
$resolved_path = resolve_path( aliases => $tree->aliases, $bootpath->data( type => 'string' ) );

DESCRIPTION

The Solaris::DeviceTree::OBP module implements functions for manipulating OBP pathes according to "IEEE 1275".

EXPORT

The following functions are exported on demand:

$p = resolve_path( aliases => $aliases, path => "/path" );

This functions transforms the specified path in an alias-free path using the path resolution procedure described in 1275.pdf - 4.3.1 Path resolution procedure according to the specified reference to an alias mapping.

EXAMPLES

In the following example the resolved physical pathname of the device last booted from is printed:

use Solaris::DeviceTree::OBP( :DEFAULT );
my $tree = new Solaris::DeviceTree;
$bootpath = $tree->find_prop( devfs_path => '/chosen', prom_prop_name => 'bootpath' );
$resolved_path = resolve_path( aliases => $tree->aliases, $bootpath->data( type => 'string' ) );
print "Last boot from $resolved_path\n";
