•

vxiint.h

contains parameter and return values for the interrupt and

signal functions.

•

sysint.h

contains parameter and return values for the system

interrupt functions.

•

trig.h

contains parameter and return values for the trigger functions.

This file is useful in VXI systems but is not applicable for VME
systems.

•

ws.h

contains parameter and return values for the Commander and

Servant Word Serial functions. This file is useful in VXI systems but
is not applicable for VME systems.

Header Files for NI-VISA

The

VXIpnp/linux/include

directory (where

VXIpnp

is the actual

location where you installed the NI-VISA software package) contains the
following include files for the C language interface:

•

visa.h

is the main header file containing the C prototypes for the

NI-VISA functions.

•

visatype.h

contains VXIplug&play data type specifications.

•

vpptype.h

contains useful definitions for instrument drivers.
