DESCRIPTION
     These functions test whether wc  is  a  wide-character  code
     representing  a  character  of a particular class defined in
     the LC_CTYPE category of the current locale.


     In all cases, wc is a wint_t, the value of which must  be  a
     wide-character  code  corresponding  to a valid character in
     the current locale or must equal  the  value  of  the  macro
     WEOF.  If the argument has any other values, the behavior is
     undefined.

     iswalpha(wc)       Tests whether wc is a wide-character code
                        representing a character of class "alpha"
                        in the program's current locale.


     isenglish(wc)      Tests whether wc is a wide-character code
                        representing  an English language charac-
                        ter, excluding ASCII characters.


     isideogram(wc)     Tests whether wc is a wide-character code
                        representing   an   ideographic  language
                        character, excluding ASCII characters.


     isnumber(wc)       Tests whether wc is a wide-character code
                        representing digit [0-9], excluding ASCII
                        characters.


     isphonogram(wc)    Tests whether wc is a wide-character code
                        representing  a phonetic language charac-
                        ter, excluding ASCII characters.


     isspecial(wc)      Tests whether wc is a wide-character code
                        representing  a  special language charac-
                        ter, excluding ASCII characters.

     iswalnum(wc)       Tests whether wc is a wide-character code
                        representing a character of class "alpha"
                        or  "digit"  in  the  program's   current
                        locale.


     iswascii(wc)       Tests whether wc is a wide-character code
                        representing an ASCII character.


     iswblank(wc)       Tests whether wc is a wide-character code
                        representing a character of class "blank"
                        in the  program's  current  locale.  This
                        function is not available to applications
                        conforming to standards prior  to  SUSv3.
                        See standards(5).


     iswlower(wc)       Tests whether wc is a wide-character code
                        representing a character of class "lower"
                        in the program's current locale.


     iswcntrl(wc)       Tests whether wc is a wide-character code
                        representing a character of class "cntrl"
                        in the program's current locale.


     iswdigit(wc)       Tests whether wc is a wide-character code
                        representing a character of class "digit"
                        in the program's current locale.


     iswgraph(wc)       Tests whether wc is a wide-character code
                        representing a character of class "graph"
                        in the program's current locale.


     iswprint(wc)       Tests whether wc is a wide-character code
                        representing a character of class "print"
                        in the program's current locale.


     iswpunct(wc)       Tests whether wc is a wide-character code
                        representing a character of class "punct"
                        in the program's current locale.


     iswspace(wc)       Tests whether wc is a wide-character code
                        representing a character of class "space"
                        in the program's current locale.
