Index

This manual describes the library of classes supplied with C++ Version 7.1 for Tru64 systems. It contains detailed information on members of these classes (including member functions) and information on other associated functions, variables, and macros.

Intended Audience

This manual is intended for experienced programmers who have a basic understanding of the C++ language, and who are using C++ with the Tru64 operating system in either a single or multiple platform environment. Some familiarity with the operating system is assumed.

Document Structure

This manual consists of an introductory chapter and 10 chapters describing each of the packages of predefined classes supplied with the C++ compiler.

C++ Documents

The following documents are provided in the C++ documentation set:

Stroustrup, The C++ Programming Language, 3rd Edition, Addison-Wesley, 1997	Provides an exhaustive introduction to the C++ programming language, and includes the text but not the annotation of The Annotated C++ Reference Manual.
Using HP C++ for OpenVMS Systems	Describes the specifics of HP's C++ implementation.
Compaq C++ Installation Guide for Tru64 UNIX	Describes how to install C++ on your system.
C++ Command Reference Pages	Provides references for C++ commands and libraries.
Musser and Saini, STL Tutorial and Reference Guide, Addison-Wesley, 1995	Describes how to use the Standard Templates Library (STL).

Changes for C++ Version 7.1 for OpenVMS I64

The following class library changes apply to C++ Version 7.1 and higher for OpenVMS I64 systems:

• The tasks and complex packages have been removed. The recommended replacements are the pthreads routines and complex template class, respectively, from the C++ standard library.
• In the String class, the char*() operator, which converts String to a pointer to char , has been removed. The String class has a const char*() operator, which can be used instead of the removed one.
