* Defines (without pulling in platform-specific network include headers):
* bswap16, bswap32, bswap64, ntoh16, hton16, ntoh32 hton32, ntoh64, hton64
*
* Should support linux / macos / solaris / windows.
* Supports GCC (on any platform, including embedded), MSVC2015, and clang,
* and should support intel, solaris, and ibm compilers as well.

C++ : Polymorphic inheritance without vtable

Inheritance and Virtual Table are often used to create interface in C++ polymorphic class
What if ... there were another way to do this ?
easier, cleaner, faster and more reliable
This article explains how to use CRTP, [std::variant](https://en.cppreference.com/w/cpp/utility/variant and std::visit to increase code performance.

You need the terminal color codes. For linux it's the following (your system might be different, look it up):

//the following are UBUNTU/LINUX, and MacOS ONLY terminal color codes.
#define RESET   "\033[0m"
#define BLACK   "\033[30m"      /* Black */
#define RED     "\033[31m"      /* Red */
#define GREEN   "\033[32m"      /* Green */
#define YELLOW  "\033[33m"      /* Yellow */
#define BLUE    "\033[34m"      /* Blue */
#define MAGENTA "\033[35m"      /* Magenta */
