Name

  iostream_intro - Introduction to the Compaq C++ Standard Library iostream
  Package

  This page is an introduction to the ANSI I/O stream classes. If you would
  like information on the pre-ANSI I/O stream package, use the command:

       man 3C++ ios_intro or man ios_intro.3C++

Description

  [ TBS ]  A more detailed description of the ANSI iostream package will be
  available in a future release of the Compaq C++ compiler.

Compatibility

  [Digital]  The ANSI Standard Library provides two macros which enable or
  disable use of the ANSI iostream package at compile time.  The ANSI
  iostream package may cause compile time and/or run time behavior
  incompatibilities which require source code changes to resolve.  These
  macros allow users to choose the iostream package they want.

  Check the cxx(3) documentation for a description of the default settings of
  these macros in different compiler modes.

  The -D Compaq C++ compiler switch can be used on the compile command line
  without requiring source code changes while the #define line should be
  added to the source code prior to any #include statement.

  All source modules within the same application must be compiled in the same
  mode.
