LabWindows/CVI Compiler
This chapter describes LabWindows/CVI compiler specifics, C language extensions, 32-bit
compiler issues, debugging levels, and user protection.
Overview
The LabWindows/CVI compiler is a 32-bit ANSI C compiler. The kernel of the
LabWindows/CVI compiler is the lcc ANSI C compiler (© Copyright 1990, 1991, 1992, 1993
David R. Hanson). It is not an optimizing compiler, but instead focuses on debugging, user
protection, and platform independence. Because the compiler is an integral part of the
LabWindows/CVI environment and features a limited set of straightforward options, it is also
easy to use.
LabWindows/CVI Compiler Specifics
This section describes specific LabWindows/CVI compiler limits, options, defines, and
diversions from the ANSI C standard.
