Creates a new Socket::Option object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1) p sockopt.int => 1 p Socket::Option.ipv4_multicast_loop(10) #=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
Returns the ipv4_multicast_loop data in sockopt as a integer.
sockopt = Socket::Option.ipv4_multicast_loop(10) p sockopt.ipv4_multicast_loop => 10
Creates a regular expression to match IPv4 addresses
Returns the max number of flags interned to symbols.
Sets the max number of flags interned to symbols.
The default mail submission port number, 587.
Enables SMTP/TLS (STARTTLS) for this object if server accepts. context is a OpenSSL::SSL::SSLContext object.
The get_attribute_ns method retrieves a method by its namespace and name. Thus it is possible to reliably identify an attribute even if an XML processor has changed the prefix.
