Detailed Description

template<typename _CharT>
struct __gnu_cxx::char_traits< _CharT >

Base class used to implement std::char_traits.

Note:
For any given actual character type, this definition is probably wrong. (Most of the member functions are likely to be right, but the int_type and state_type typedefs, and the eof() member function, are likely to be wrong.) The reason this class exists is so users can specialize it. Classes in namespace std may not be specialized for fundamentl types, but classes in namespace __gnu_cxx may be.
See http://gcc.gnu.org/onlinedocs/libstdc++/21_strings/howto.html#5 for advice on how to make use of this class for "unusual" character types. Also, check out include/ext/pod_char_traits.h.
