Linux::Sysfs::Device - sysfs devices
my $device = Linux::Sysfs::Device->open($bus, $bus_id); my $parent = $device->get_parent; my @attrs = $device->get_attrs; $device->close;
Devices represent everything in sysfs under /sys/devices, which is a hierarchical view of system devices.
my $device = Linux::Sysfs::Device->open($bus, $bus_id);
Given the name of the
$bus, this method locates a given device and returns a Linux::Sysfs::Device instance corresponding to the requested
my $device = Linux::Sysfs::Device->open_path($path);
Opens up a device at a specific
$path. It opens the device's directory, reads the directory, and returns a Linux::Sysfs::Device instance on success or undef on failure.
Closes up the
Closes every device under the supplied root
my $parent = $device->get_parent;
Returns the Linux::Sysfs::Device instance for the parent (if present) of the given
$device->get_bus or die 'get_bus failed';
Fills in the bus this
$device is on. The Linux::Sysfs::Bus instance can be retrieved using the bus() method later on. Returns something true on success or something false on failure.
my $attr = $device->get_attr($name);
$device's attributes by
$name and returns the corresponding Linux::Sysfs::Attribute instance or undef.
my @attrs = $device->get_attrs;
Returns a list of Linux::Sysfs::Attribute instances for the
my $name = $device->name;
Returns the name of the device.
my $path = $device->path;
Returns the full path of the device in sysfs.
my $bus_id = $device->bus_id;
$device's bus id.
my $bus = $device->bus;
Returns the Linux::Sysfs::Bus instance this
$device is on. You'll need to call get_bus() first.
my $driver_name = $device->driver_name;
Returns the name of the driver responsible for the device.
