LabWindows/CVI Programmer Reference Manual

This chapter describes LabWindows/CVI compiler specifics, C language extensions, 32-bit 
compiler issues, debugging levels, and user protection.

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.

This section describes specific LabWindows/CVI compiler limits, options, defines, and 
diversions from the ANSI C standard.

Table 1-1 shows the compiler limits for LabWindows/CVI.
