SYNOPSIS

     #include <wchar.h>

     int iswalpha(wint_t wc);

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.

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

     iswlower(wc)
           Tests whether wc is a wide-character code representing
           a  character of class "lower" 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.

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

     iswalnum(wc)
           Tests whether wc is a wide-character code representing
           a  character  of  class  "alpha"  or  "digit"  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.

     iswpunct(wc)
           Tests whether wc is a wide-character code representing
           a  character of class "punct" 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.

     iswgraph(wc)
           Tests whether wc is a wide-character code representing
           a  character of class "graph" 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.

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

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

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

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

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

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