template<typename_CharT>
       class std::__ctype_abstract_base< _CharT >"Common base for ctype facet.

       This template class provides implementations of the public functions that forward to the protected
       virtual functions.

       This template also provides abstract stubs for the protected virtual functions.

template<typename_CharT>virtualconstchar_type*std::__ctype_abstract_base<_CharT>::do_is(constchar_type*__lo,constchar_type*__hi,mask*__vec)const[protected],[purevirtual]
       Return a mask array. This function finds the mask for each char_type in the range [lo,hi) and
       successively writes it to vec. vec must have as many elements as the input.

       do_is() is a hook for a derived facet to change the behavior of classifying. do_is() must always return
       the same result for the same input.

       Parameters__lo Pointer to start of range.
           __hi Pointer to end of range.
           __vec Pointer to an array of mask storage.

       Returns__hi.

       Implemented in std::ctype<_CharT>, and std::ctype<wchar_t>.

   template<typename_CharT>virtualboolstd::__ctype_abstract_base<_CharT>::do_is(mask__m,char_type__c)const[protected],[purevirtual]
       Test char_type classification. This function finds a mask M for c and compares it to mask m.

       do_is() is a hook for a derived facet to change the behavior of classifying. do_is() must always return
       the same result for the same input.

       Parameters__c The char_type to find the mask of.
           __m The mask to compare against.

       Returns
           (M & __m) != 0.

   template<typename_CharT>virtualcharstd::__ctype_abstract_base<_CharT>::do_narrow(char_type__c,char__dfault)const[protected],[purevirtual]
       Narrow char_type to char. This virtual function converts the argument to char using the simplest
       reasonable transformation. If the conversion fails, dfault is returned instead.

       do_narrow() is a hook for a derived facet to change the behavior of narrowing. do_narrow() must always
       return the same result for the same input.

       Note: this is not what you want for codepage conversions. See codecvt for that.
