18 TCP Redirect: tcp^ via Channels
| (require net/tcp-redirect) | package: net-lib |
The net/tcp-redirect
library provides a function for directing some TCP port numbers to use
buffered channels instead of the TCP support from
racket/tcp.
procedure
(tcp-redirect port-numbers) → unit?
port-numbers : (listof (integer-in 0 65535))
Returns a unit that implements tcp^. For port numbers not
listed in port-numbers, the unit’s implementations are the
racket/tcp implementations.
For the port numbers listed in port-numbers and for connections to "127.0.0.1", the unit’s implementation does not use TCP connections, but instead uses internal buffered channels. Such channels behave exactly as TCP listeners and ports.
