/* Title : VISA.H */
/* Date : 06-15-2004 */
/* Purpose : Include file for the VISA Library 3.0 specification */
/* */
/*---------------------------------------------------------------------------*/
/* When using NI-VISA extensions, you must link with the VISA library that */
/* comes with NI-VISA. Currently, the extensions provided by NI-VISA are: */
/* */
/* PXI (Compact PCI eXtensions for Instrumentation) and PCI support. To use */
/* this, you must define the macro NIVISA_PXI before including this header. */
/* You must also create an INF file with the VISA Driver Development Wizard. */
/* */
/* A fast set of macros for viPeekXX/viPokeXX that guarantees binary */
/* compatibility with other implementations of VISA. To use this, you must */
/* define the macro NIVISA_PEEKPOKE before including this header. */
/* */
/* Support for USB devices that do not conform to a specific class. To use */
/* this, you must define the macro NIVISA_USB before including this header. */
/* You must also create an INF file with the VISA Driver Development Wizard. */
