Language Interface: 16-bit Microsoft Visual C/C++

This is the GPIB language interface for Microsoft Visual C/C++ (version 1.0), a Windows 3 programming environment for creating 16-bit applications. (Note that version 1.0 is also known as Microsoft C/C++ version 8.0.) Download the Msc.zip file (in the example.zip file, below). This file contains the declaration file WINDECL.H, the language interface file GPIB.LIB, and some sample programs.


How to Use the 16-bit Microsoft Visual C/C++ Language Interface:

I. Overview

The 16-bit GPIB language interface for Microsoft Visual C/C++ contains the following files:

WINDECL.H: Win16 C/C++ include file

GPIB.LIB: Win16 C/C++ language interface module

If you have the GPIB Software for Windows 3 installed, the C/C++ language interface and the sample applications are located in the directory called \C (where is where the GPIB software for Windows 3 is installed). The sample applications are QuickWin applications (see below).


II. Items to Include in Your GPIB Application

You must include the following line at the beginning of your application:

#include "windecl.h"

Next you need to include the GPIB.LIB file in your application's project file along with your application.
[ Note: The required key strokes and menu bar selections needed in order to add a file to a project can vary with different versions of that particular compiler. For information about how to add files, please refer to the manuals and online help that came with your version of the compiler. ]


III.A. Compiling, Linking, and Running from the Microsoft Visual C/C++ Environment

From within the Microsoft environment, you can compile, link, and run your application.

To compile the GPIB sample applications, you need to select QuickWin as the Project type.

[ Note: The required key strokes and menu bar selections needed in order to create, compile, and link a project vary with different versions of that particular compiler. For information about how to add files, compile, link, and run a project, please refer to the manuals that came with your version of the compiler. ]


III.B. Compiling, Linking, and Running from the DOS Command Line

From the DOS command line, type in the following in order to compile and link a QuickWin application, called yourprog, with the C/C++ language interface, GPIB.LIB:

cl /Mq yourprog.c gpib.lib

To run the newly created executable, type in the name of your application on the DOS command line, like so:

yourprog


IV. QuickWin

Microsoft C/C++ has a compiler option called QuickWin (the /Mq switch on the command-line compiler). The GPIB sample programs are of the this type. They illustrate how to use the function calls exported by the GPIB driver. It is simple to create Windows applications without knowledge of Windows Graphical User Interface (GUI) programming. A QuickWin application is a Windows program which uses text-based input and output, not a graphical interface. This allows you to quickly create a Windows application by using simple input and output functions like printf and scanf.
