A tcp/ip pipe is a user space programme that listens for tcp/ip connections on port on the local host and when a client connects makes a connection to a tcp port, possibly on another host. once both connections are established data sent on one connection is relayed to the other, hence forming a bi-directional pipe.

uses include enabling connections to specific ports on hosts behind a packet filter.

this code is intended primarily as an example of how many of the features of libvanessa_socket work.
