Demo 1: Marking a square and a triangle
// File
// DEMO1.cpp
//
// Abstract
// A console application for marking a square and a triangle
// by using a CO2 laser
//
// Author
// Bernhard Schrems, SCANLAB AG
//
// Comment
// Besides demonstrating of how to initialize the RTC4 and how to
// perform marking, this application also shows how to implicitly
// link to the RTC4DLL.DLL. For accomplishing implicit linking -
// also known as static load or load-time dynamic linking of a DLL,
// the header file RTC4impl.H is included and for building the
// executable, you must link with the (Visual C++) import library
// RTC4DLL.LIB.
// In case the operating system does not find the RTC4DLL.DLL on
// program startup, it will respond with a corresponding error
// message and it will terminate the program.
//
// Necessary Sources
// RTC4impl.H, RTC4DLL.LIB, MESSAGE.CPP
// NOTE: RTC4DLL.LIB is a Visual C++ library.
//
// Environment: Win32
//
// Compiler
// - tested with Visual C++ 5.0 and Visual C++ 6.0
// system header files
#include <stdio.h>
#include <conio.h>
// RTC4 header file
#include "rtc4impl.h"
