C++ iostream Library - wout Object


Advertisements

Description

The object of class wostream that represents the standard output stream oriented to wide characters (of type wchar_t). It corresponds to the C stream stdout. The standard output stream is the default destination of characters determined by the environment. This destination may be shared with more standard objects (such as wcerr or wclog).

Oject of a basic_ostream class, characters can be written to it either as formatted data using the insertion operator (operator<<) or as unformatted data, using member functions such as write.

Declaration

Following is the declaration for std::wout.

extern basic_ostream<wchar_t> wcout;

By default, wcout is synchronized with stdout.

A program should not mix output operations on wcout with output operations on cout (or with other narrow-oriented output operations on stdout): Once an output operation has been performed on either, the standard output stream acquires an orientation (either narrow or wide) that can only be safely changed by calling freopen on stdout..
