Iterates the given block for each element with an index, which starts from offset. If no block is given, returns a new Enumerator that includes the index, starting from offset

offset

the starting index to use

Like Enumerable#select, but chains operation to be lazy-evaluated.

Returns the Object#object_id of the internal object.

Loads the given private key identified by id and data.

An EngineError is raised of the OpenSSL::PKey is unavailable.

Extracts addr from IPV6_PKTINFO ancillary data.

IPV6_PKTINFO is defined by RFC 3542.

addr = Addrinfo.ip("::1")
ifindex = 0
ancdata = Socket::AncillaryData.ipv6_pktinfo(addr, ifindex)
p ancdata.ipv6_pktinfo_addr #=> #<Addrinfo: ::1>

Creates a new Socket::Option object for IP_MULTICAST_TTL.

The size is dependent on the platform.

p Socket::Option.ipv4_multicast_ttl(10)
#=> #<Socket::Option: INET IP MULTICAST_TTL 10>

Returns the ipv4_multicast_ttl data in sockopt as an integer.

sockopt = Socket::Option.ipv4_multicast_ttl(10)
p sockopt.ipv4_multicast_ttl => 10

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 an integer.

sockopt = Socket::Option.ipv4_multicast_loop(10)
p sockopt.ipv4_multicast_loop => 10

Load an iseq object from binary format String object created by RubyVM::InstructionSequence.to_binary.

This loader does not have a verifier, so that loading broken/modified binary causes critical problem.

You should not load binary data provided by others. You should use binary data translated by yourself.

Create a new DRbObject from a URI alone.

Check that a method is callable via dRuby.

obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.

If the method is an insecure method (see insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.
