Intro -- introduction to C++ library classes

Description

This section contains manual pages for the classes and routines in two older, non-standard C++ libraries. These are provided primarily for compatibility with existing applications. Manual pages for the classes and routines in the new ISO C++ Standard Library are provided in section 3C++std; they should be used whenever possible.

The two libraries described in this section are:

The old de facto AT&T C++ "standard library" which provided the new functions and complex and iostreams classes before the ISO standard for C++ was developed. These classes are in the global namespace, not namespace std, and are accessed by including the .h-suffixed forms of header files (for example, by including <new.h> rather than <new> or <iostream.h> rather than <iostream>. The iostreams classes in this library are not thread-safe.
C++ Standard Components. This is a foundation class library which has a large amount of functional overlap with the ISO C++ Standard Library. These classes and routines are in namespace SCO_SC. They are not thread-safe. To ease compilation of existing usages of C++ Standard Components, compiling with -DUSING_SCO_SC will generate "using namespace SCO_SC;" using directives at the end of each Standard Component header. This will allow you to compile existing code without changing it to reference the namespace.

Standards compliance

As described above, the classes and routines in this section are not part of the ISO C++ Standard Library.
