Introduction

Several times you are required to call an C++ code from a C code. One example where you want to have such interoperability is when you use an operational system, as for example VxWorks realtime program, where the program executions requires an entry-point in C code. On this article it is proposed a 3 step procedure that will allow you to execute such interoperability.

Step 1 - Create an Interoperability Header (CodeInteroperability.h)

This header will contain your entry point class and 3 additional global functions to Create, Run and Destroy your entry point class.

Step 2 - Codify your entry point class and the 3 global functions using C++ (CodeInteroperability.cpp)

Step 3 - Use the 3 global functions on the C program (CEntryPoint.c)
