Constructor Details

#initialize(addr, port = nil, options = {}) ⇒ TCPListener

Create a new Coolio::TCPListener on the specified address and port. Accepts the following options:

:backlog - Max size of the pending connection queue (default 1024)
:reverse_lookup - Retain BasicSocket's reverse DNS functionality (default false)

If the specified address is an TCPServer object, it will ignore the port and :backlog option and create a new Coolio::TCPListener out of the existing TCPServer object.
