Sample C Program - Generating a Service Request
Segments of the sample C program "gen_srq.c" show how to initialize the
interface and oscilloscope, and generate a service request.
Two include statements start the "gen_srq.c" program. The file "stdio.h" defines
the standard location of the printf routine, and is needed whenever input or
output functions are used. The file "gpibdecl.h" includes necessary prototypes
and declarations for the Infiniium-Series Oscilloscopes sample programs. The
path of these files must specify the disk drive and directory where the "include"
files reside.
/* location of: printf() */
/* initialize interface and device sessions */
/* close interface and device sessions */
The routine "init_IO" contains three subroutines that initialize the oscilloscope
and interface, and sets up and generate a service request.
The following segment describes the initialize subroutine.
