#

The object wcin controls input from a stream buffer associated with the object stdin, declared in .

#

After the objectwcin is initialized,wcin.tie() returns&wcout.

Its state is otherwise the same as required forbasic_ios<wchar_t>​::​init.

#

The object wcout controls output to a stream buffer associated with the object stdout, declared in .

wostream wcerr;

#

The object wcerr controls output to a stream buffer associated with the object stderr, declared in .

5

#

After the objectwcerr is initialized,wcerr.flags() & unitbuf is nonzero and wcerr.tie() returns &wcout.

Its state is otherwise the same as required forbasic_ios<wchar_t>​::​init.
