NAME ^

Linux::Sysfs - Perl interface to libsysfs

VERSION ^

Version 0.03

SYNOPSIS ^

    use Linux::Sysfs;

    my $path = Linux::Sysfs->get_mnt_path();

    my $module = Linux::Sysfs::Module->open('usbcore');
    my @parms  = $module->get_sections;

    $module->close;

DESCRIPTION ^

Linux::Sysfs' purpose is to provide a consistent and stable interface for querying system device information exposed through the sysfs filesystem. The library implements functions for querying filesystem information, such as reading directories and files. It also contains routines for working with buses, classes, and the device tree.

The functionality of this module is split up between several packages. See the other packages under the Linux::Sysfs:: namespace for the full documentation.

EXPORT ^

The following libsysfs constants may be imported.

$FSTYPE_NAME
$PROC_MNTS
$BUS_NAME
$CLASS_NAME
$BLOCK_NAME
$DEVICES_NAME
$DRIVERS_NAME
$MODULE_NAME
$NAME_ATTRIBUTE
$MOD_PARM_NAME
$MOD_SECT_NAME
$UNKNOWN
$PATH_ENV

All constants will be exported when using the ':all' tag when importing.

FUNCTIONS ^

get_mnt_path

  my $path = Linux::Sysfs->get_mnt_path();

Finds the mount path for filesystem type "sysfs". Returns undef on failure.

DEPENDENCIES ^

Linux::Sysfs requires libsysfs version 2.0.0 or later. See http://linux-diag.sourceforge.net/Sysfsutils.html.

INCOMPATIBILITIES ^

This module currently doesn't work with any version of libsysfs smaller than 2.0.0.

BUGS AND LIMITATIONS ^

In the current implementation of Linux::Sysfs it's not possible to free the objects when they get destroyed automatically. Therefor you should care about calling close() for each object when you don't need it anymore.
