pw_dumb_io_stdio
----------------
The ``pw_dumb_io_stdio`` backend implements the ``pw_dumb_io`` facade using
stdio.
Why not just use stdio directly?
--------------------------------
The nice thing about using ``pw_dumb_io`` is that it's rather easy to get a
board up and running with a target-specific backend. This means when drafting
out a quick application you can write it against ``pw_dumb_io`` and, with some
care, the application will be able to run on both host and target devices.
While it's not recommended to use ``pw_dumb_io`` for any production
applications, it can be rather helpful for early prototyping.
Setup
=====
This module requires relatively minimal setup:
1. Write code against the ``pw_dumb_io`` facade.
2. Specify the ``dir_pw_dumb_io_backend`` GN global variable to point to this
backend.
Module usage
============
For the most part, applications built with this backend will behave similarly
to an application built directly against stdio.
Dependencies
============
