Choosing Your Programming Methodology
Based on your development environment, you can select a method for
accessing the driver, and based on your NI-488.2 programming needs,
you can choose how to use the NI-488.2 API.
Choosing a Method to Access the NI-488.2 Driver
Windows
Applications using the older GPIB32 API can access the NI-488.2 dynamic
link library (DLL),
gpib-32.dll , either by using an NI-488.2 application
interface or by direct access.
Applications using the new NI4882 API can access the NI-488.2 dynamic
link library (DLL),
ni42882.dll , by using an NI-488.2 application
interface only.
NI-488.2 Application Interfaces
You can use an application interface if your program is written in Microsoft
Visual C/C++ (6.0 or later), Borland C/C++ (5.02 or later), Microsoft
Visual Basic (6.0), or any .NET programming language. Otherwise, you
must access
gpib-32.dll directly.
For more information about application interfaces, refer to NI-488.2
Application Interface Files in the NI-488.2 Help.
Direct Entry Access
You can access the DLL directly from any programming environment that
allows you to request addresses of variables and calls that a DLL exports.
gpib-32.dll exports pointers to each of the global variables and all the
NI-488.2 calls.
