Class Method Details

.build(*args) ⇒ Object

# File 'lib/dat-tcp.rb', line 200

def self.build(*args)
  case args.size
  when 2
    self.new(*args)
  when 1
    self.for_fd(*args)
  end
end

.configure(tcp_server) ⇒ Object

‘setsockopt` values:

• SOL_SOCKET - specifies the protocol layer the option applies to.

  SOL_SOCKET is basic socket options (as opposed to
  something like IPPROTO_TCP for TCP socket options).
  

• SO_REUSEADDR - indicates that the rules used in validating addresses

  supplied in a bind(2) call should allow reuse of local
  addresses. This will allow us to re-bind to a port if
  we were shutdown and started right away. This will
  still throw an "address in use" if a socket is active
  on the port.
