@defmodule[net/tcp-redirect]{The @racketmodname[net/tcp-redirect]
|
|
library provides a function for directing some TCP port numbers to use
|
|
buffered channels instead of the TCP support from
|
|
@racketmodname[racket/tcp].}

@defproc[(tcp-redirect [port-numbers (listof (integer-in 0 65535))])

unit?]{
|
|
|
|
Returns a unit that implements @racket[tcp^]. For port numbers not
|
|
listed in @racket[port-numbers], the unit's implementations are the
|
|
@racketmodname[racket/tcp] implementations.
|
|
|
|
For the port numbers listed in @racket[port-numbers] and for
|
|
connections to @racket["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.}
