Cray Standard C++ [4]
The Cray Standard C++ compiler together with the Dinkum C++ Libraries
support the C++98 standard (ISO/IEC FDIS 14882) and continues to support
existing Cray extensions. Most of the standard C++ features are supported,
except for the few mentioned in Section 4.1, page 103.
The Dinkum C++ Library documentation, describes the Dinkum C++ Library
and is mainly a reference. This documentation is described in Section 4.2,
page 103.
4.1 Unsupported Standard C++ Features
The Cray Standard C++ compiler supports the C++ standard except for the
features mentioned here. These features are wide characters and multiple locales
as the following shows:
String classes using basic string class templates with wide character types
or that use the wstring standard template class
I/O streams using wide character objects
File-based streams using file streams with wide character types (wfilebuf,
wifstream, wofstream, and wfstream)
Multiple localization libraries. Cray standard C++ supports only one locale.
Note: The C++ standard provides a standard naming convention for library
routines. Therefore, classes or routines that use wide characters are named
appropriately. For example the following contrasts routines that do not use
wide characters and those that do: fscanf and fwscanf, sprintf and
swprintf)
4.2 Dinkum C++ Libraries
The Cray standard C++ compiler uses the Dinkum C++ libraries which supports
standard C++. In order to understand the library you can use the Dinkum C++
Library documentation. This documentation is provided only in HTML form
and can be found on your CrayDoc CD, where your administrator installed the
documentation, or on the public web site for Cray Inc. documentation. You
can also find other references to tutorials and advanced user materials for the
standard C++ library in Related Publications. Refer to CrayDoc Installation and
