Constructor Details

#initialize(host, service, local_host = nil, local_service = nil) ⇒ TCPSocket

call-seq:

TCPSocket.new(host, service, local_host=nil, local_service=nil) -> tcpsocket

Creates a new TCP socket connected to the given host and service. Optionally binds to local_host and local_service first.

sock = TCPSocket.new("localhost", 80)
sock = TCPSocket.new("www.example.com", "http")
sock = TCPSocket.new("remote", 80, "127.0.0.1", 12345)
