Chapter 4GPIB/GPIB-488.2 Library

This describes the NI-488 and NI-488.2 functions in the LabWindows/CVI GPIB Library, as

well as the Device Manager functions in LabWindows/CVI. The GPIB Library Function

Overview section contains general information about the GPIB Library functions and panels, the

GPIB DLL, and guidelines and restrictions you should know when using the GPIB Library.

Detailed descriptions of the NI-488 and NI-488.2 functions can be found in your NI-488.2

function reference manual. The GPIB Function Reference section contains an alphabetical list of

descriptions for the Device Manager functions, the callback installation functions, and the

functions for returning the thread-specific status variables.

This section describes the functions in the LabWindows/CVI GPIB Library. These functions are

arranged alphabetically according to their names in C. For detailed function descriptions, refer to

the NI-488.2 function reference manual that accompanied your GPIB interface board.

The GPIB Functions Library function panels are grouped in a tree structure according to the

types of operations performed. The GPIB Functions Library function tree is in Table 4-1.

The first- and second-level bold headings in the function tree are names of the function classes.

Function classes are groups of related function panels. The third-level headings in plain text are

the names of individual function panels. Each GPIB function panel generates a GPIB function

call. The actual function names are in bold italics in columns to the right.
