OS detection

Introduction

This module has for purpose to detect the kind of Operating System (OS) the build is executed in using the tool uname -a. It is supporting:

• Ubuntu

• MacOs

• PREEMPT_RT

• Xenomai

It defines the following C/C++ preprocessor macros:

• XENOMAI (if Xenomai is detected)

• RT_PREEMPT (if PREEMPT_RT OS is found)

• MAC_OS (if MacOS is detected)

• NON_REAL_TIME (if non-real-time OS is detected)

The real_time_tools package depends heavily on this detection.

Usage

There is a macros called define_os() that is called by default if one depend on this pacakge, see [readme.md](@ref md_readme). So basically there is nothing specific to be done to use this tool.
