38// Class basic_ios, a subclass of ios_base. The only important difference
39// between the two is that basic_ios is a class template, parameterized
40// by the character type. ios_base exists to factor out all of the
41// common properties that don't depend on the character type.
42
43// The second template parameter, _Traits, defaults to char_traits<_CharT>.
44// The default is declared in header <iosfwd>, and it isn't declared here
45// because C++ language rules do not allow it to be declared twice.
