returns the socket family as an integer.
p Socket::AncillaryData.new(:INET6, :IPV6, :PKTINFO, "").family #=> 10
Creates a new Socket::AncillaryData object which contains a int as data.
The size and endian is dependent on the host.
require 'socket' p Socket::AncillaryData.int(:UNIX, :SOCKET, :RIGHTS, STDERR.fileno) #=> #<Socket::AncillaryData: UNIX SOCKET RIGHTS 2>
Returns the data in ancillarydata as an int.

p Socket::Option.new(:INET, :SOCKET, :KEEPALIVE, [1].pack("i")).inspect #=> "#<Socket::Option: INET SOCKET KEEPALIVE 1>"
Creates a new Socket::Option object which contains an int as data.
The size and endian is dependent on the platform.
p Socket::Option.int(:INET, :SOCKET, :KEEPALIVE, 1) #=> #<Socket::Option: INET SOCKET KEEPALIVE 1>
