TNS/R Native C and C++ Migration Tool

The native C and C++ migration tool, NMCMT, scans source files and produces a

diagnostic listing. The listing identifies most C and C++ language source code changes

required to migrate from TNS C (D20 or later product versions) to native C or C++.

The native mode migration tool is available in both the Guardian and OSS

environments, and it is integrated into the HP Enterprise Toolkit on the PC.

Features of TNS/R Native C and C++

Over the years, TNS/R native C and C++ have evolved as the languages themselves

were changing.

•

At the D40 release, the TNS/R native C/C++ compiler accepted the language as

defined by The Annotated C++ Reference Manual by Ellis and Stroustrup

(excluding support for exception handling).

•

At D45, some features were updated to match the language specification in the

1996 X3J16/WG21 Working Paper. VERSION2 of the native C++ compiler is

based on the 1996 standard. The native C++ compiler introduced support for

exceptions and a number of features that are not in the The Annotated C++

Reference Manual but are new in the working paper. A summary of the major

features added at D45 appears in the description of pragma VERSION2 on

page 13-106. A list of specific features accepted from the working paper appears in

Appendix E, Features and Keywords of Version 2 Native C++.

•

At G06.20, a new version or dialect of the native C++ compiler was introduced.

VERSION3 of the compiler is based on the 1998 standard, listed in the references

that follow. VERSION3 is the default library used by the native C++ compiler.

This manual is not intended to be a reference manual for ANSI C or for C++. For a

complete description of ANSI C, see ANSI X3.159. For a complete description of C++,

see ANSI X3J16/96-0225 (VERSION2) and ISO/IEC 14882:1998(E) (VERSION3).
