VERSION3
For VERSION3, the Standard C++ Library ANSI/ISO/IEC is a port of the Dinkumware
C++ Library, a conforming implementation of the Standard C++ library by P.J. Plauger.
The library enforces the ISO/IEC IS 14882:1998(E) standard for C++, plus a number of
fixes ratified by the C++ Standards Committee and documented in corrigenda before
the NonStop VERSION3 code was developed and finalized.
A C++ program can call on a large number of functions from the Dinkum C++ Library
that perform essential services such as input and output. These functions also provide
efficient implementations of frequently used operations. Numerous function and class
definitions accompany these functions to help you make better use of the library.
Information about the Standard C++ library can be found in the descriptions of the C++
library headers that declare or define library entities for the program. Also see the
documentation for the library, the Standard Compliant C++ Library Reference, available
on the NonStop user CD using the HP NonStop Technical Library (NTL).
There are two broad subdivisions of the Standard C++ headers: streams and the
standard template library (STL).
The VERSION3 Standard C++ Library contains 36 C++ headers:
<algorithm> <bitset> · <complex> <deque> <exception> <fstream> ·
<functional> <hash_map> <hash_set> <iomanip> <ios> <iosfwd> ·
<iostream> <istream> <iterator> <limits> <list> <locale> ·
<map> <memory> <new> <numeric> <ostream> <queue> ·
<set> <slist> <sstream> <stack> <stdexcept> <streambuf> ·
<string> <strstream> <typeinfo> <utility> <valarray> <vector>
Migration tool To help customers move from C++ VERSION2 to C++
VERSION3, the migration tool generates warnings in the listing
file where potential problems are found. The
MIGRATION_CHECK pragma is described in
MIGRATION_CHECK
on page 13-62, and its output is
described in Appendix F, MIGRATION_CHECK Messages.
Hash tables Although not part of the standard, HASH_SET,
HAS_MULTISET, HASH_MAP, and HASH_MULTIMAP have
been implemented in the HP NonStop C++ implementation.
Support for the neutral
C++ dialect on NonStop
NS-series systems
Although not part of the standard, HP provides the features
described in Using the Neutral C++ Dialect
on page 5-13.
These features take advantage of the repackaging of C++
objects on NonStop NS-series systems into three library files
so that a limited ability exists to create libraries that are not
version dependent.
