Linux::Sysfs::Bus - sysfs buses
my $bus = Linux::Sysfs::Bus->open('pci'); my @devices = $bus->get_devices; my @drivers = $bus->get_drivers; $bus->close;
The library provides functions for viewing buses represented in sysfs.
my $bus = Linux::Sysfs::Bus->open($name);
Opens up one of the buses represented in sysfs in the /sys/bus directory.
$nameis the name of the bus to open (e.g. "pci"). It returns a Linux::Sysfs::Bus instance on success or undef on failure.
Closes up the sysfs_bus structure including its devices, and drivers and the list of attributes.
my @devices = $bus->get_devices;
Returns a list of Linux::Sysfs::Device instances that are registered with this bus.
my @drivers = $bus->get_drivers;
Returns a list of Linux::Sysfs::Driver instances that are registered with this bus.
my $device = $bus->get_device($id);
Looks for a device with the given
$idon this bus. On success, it returns a Linux::Sysfs::Device instance, otherwise undef.
my $driver = $bus->get_driver($name);
Looks for a driver with the given
$nameon this bus. On success, it returns a Linux::Sysfs::Driver instance, otherwise undef.
my $name = $bus->name;
Returns the bus' name.
