template<typename_CharT>virtualconstchar_type*std::ctype<_CharT>::do_is(constchar_type*__lo,constchar_type*__hi,mask*__vec)const[protected],[virtual],[inherited]
       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.

       Implements std::__ctype_abstract_base<_CharT>.

   template<typename_CharT>virtualboolstd::ctype<_CharT>::do_is(mask__m,char_type__c)const[protected],[virtual],[inherited]
       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.

       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.
