Using DEVQUERY
This C++ sample application is a Win32 console application. It illustrates how to use the Keithley
Instruments, Inc. IOUtils command. A Win32 console application is a Win32 application that uses
text-based input and output, not a graphical interface. You can quickly create a Win32 application
by using simple input and output functions.
