IO::Socket::Netlink::Generic - Object interface to NETLINK_GENERIC netlink protocol sockets
IO::Socket::Netlink::Generic
NETLINK_GENERIC
use IO::Socket::Netlink::Generic; my $genlsock = IO::Socket::Netlink::Generic->new or die "socket: $!"; printf "TASKSTATS family ID is %d\n", $genlsock->get_family_by_name( "TASKSTATS" )->{id};
This subclass of IO::Socket::Netlink implements the NETLINK_GENERIC protocol. It is itself intended to serve as a base class for particular generic families to extend.
$class->register_family_name( $name )
Must be called by a subclass implementing a particular protocol family, to declare its family name. The first time a socket in that class is constructed, this name will be looked up into an ID number.
$family = $sock->get_family_by_name( $name )
$family = $sock->get_family_by_id( $id )
Query the kernel for information on the NETLINK_GENERIC family specifed by name or ID number, and return information about it. Returns a HASH reference containing the following fields:
Sockets in this class provide the following extra field accessors on their message objects:
$message->cmd
ID number of the command to give to the family
$message->version
Version number of the interface
$message->genlmsg
Accessor for the trailing data buffer; intended for subclasses to use
