Description

Channels are buffered reader/writers built on top of unbuffered FLOW implementations.

Example:

module Channel = Channel.Make(Flow)
...
Channel.read_exactly ~len:16 t
>>= fun bufs -> (* read header of message *)
let payload_length = Cstruct.(LE.get_uint16 (concat bufs) 0) in
Channel.read_exactly ~len:payload_length t
>>= fun bufs -> (* payload of message *)

(* process message *)

Channel.write_buffer t header;
Channel.write_buffer t payload;
Channel.flush t
>>= fun () ->

Installation

mirage-channel can be installed with opam:

opam install channel

If you don't use opam consult the opam file for build instructions.

Documentation

The documentation and API reference is automatically generated by ocamldoc from the interfaces. It can be consulted online and there is a generated version in the doc directory of the distribution.

Sample programs

If you installed mirage-channel with opam sample programs are located in the directory opam config var channel:doc.

In the distribution sample programs and tests are located in the test directory of the distribution. They can be built with:

./build test

The resulting binaries are in _build/test.

  • test.native tests the library, nothing should fail.
