std::basic_filebuf<CharT,Traits>::overflow

protected : virtual int_type overflow ( int_type c = Traits:: eof ( ) ) ;

Writes some data from the put area to the associated character sequence (to the file).

Behaves like the base class std::basic_streambuf::overflow, except that to write the data, first uses std::codecvt::out

If std::codecvt::always_noconv is true, the call to std::codecvt::out

If the conversion fails with std::codecvt_base::error, returns Traits::eof()

If the associated file is not open (is_open() == false), returns Traits::eof()

Parameters

(none)

Return value

Traits::not_eof(c) to indicate success or Traits::eof()
