__gnu_cxx::_Char_types3

Mapping from character type to associated types.

Usage

#include <char_traits.h>

Public Types

typedef unsigned long int_type
typedef std::streamoff off_type
typedef std::streampos pos_type
typedef std::mbstate_t state_type

Detailed Description

template<typename _CharT>

struct __gnu_cxx::_Char_types< _CharT >"Mapping from character type to associated types.

Note

This is an implementation class for the generic version of char_traits. It defines int_type, off_type, pos_type, and state_type. By default these are unsigned long, streamoff, streampos, and mbstate_t. Users who need a different set of types, but who don't need to change the definitions of any function defined in char_traits, can specialize __gnu_cxx::_Char_types while leaving __gnu_cxx::char_traits alone.
