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.
