/*
This file provides declaration of
communication functions to be used by MIMPI implementation.
Overview rules to apply:
- replace `pipe` with `channel`
- replace `write` (or any other file writing function) with `chsend` when used on channel's fd
- replace `read` (or any other file reading function) with `chrecv` when used on channel's fd
