The GNU C++ Iostream Library - Ostream

Managing output streams: class ostream

Objects of class ostream inherit the generic methods from ios , and in addition have the following methods available. Declarations for this class come from `iostream.h'.

Constructor ostream::ostream ()

The simplest form of the constructor for an ostream simply allocates a new ios object.

Constructor ostream::ostream (streambuf* sb [, ostream tie])

This alternative constructor requires a first argument sb of type streambuf* , to use an existing open stream for output. It also accepts an optional second argument tie, to specify a related ostream* as the initial value for ios::tie .

If you give the ostream a streambuf explicitly, using this constructor, the sb is not destroyed (or deleted or closed) when the ostream is destroyed.
