I am trying to control NI's GPIB-USB-adaptor from my own source code. According to http://www.ni.com/example/29321/en/ I need decl-32.h but I can find it nowhere. Where to get it?
Download the Msvc.exe file (in the example.zip file, below). This file contains the declaration file DECL-32.H, the language interface file GPIB-32.OBJ, and some sample programs. This download is not necessary when using the latest version of NI-488.2. NI-488.2 includes files for all supported programming environments.
