This article explains how to call C++ code from Kotlin Native using a C Bridge

The purpose of C Bridge is to overcome the short comings of Kotlin Native which does not support C++ interop

Therefore we create a C library and call the C++ codes in that code and then the C code is linked to Kotlin Native code

Important Note: this is not JNI, this is Kotlin Native which directly becomes an EXE file

C++ code which std::string

This article demonstrate an unique technique of doing integration testing using

ReflectionTestUtils.setField

For a difference the code written on top of SQLite instead of H2

usage of ReflectionTestUtils

This Article demonstrates how to parse xml in Kotlin Native using libxml2 and libxslt 

If the devloper working in linux, then the developer can install libxml and libxslt 

For example in Ubuntu Focal

sudo apt-get -y install libxml2 libxml2-dev libxml2-utils
sudo apt-get -y install libxslt1-dev libxslt1.1

if the developer user windows, then the developer can install MSYS2 and install the libraries

Understanding the vertex coordinates and corresponding indices slightly complicated. 
Sometimes the developer gets carried away due to too many numbers needs to be maintained in the VBO array

This article gives a typical approach to number in counter clockwise and group indices same way

Let us go by step by step
