    SYNOPSIS

       #include <wctype.h>
    int iswalnum (wint_t wc);
    int iswalpha (wint_t wc);
    int iswascii (wint_t wc);
    int iswblank (wint_t wc);
    int iswcntrl (wint_t wc);
    int iswdigit (wint_t wc);
    int iswgraph (wint_t wc);
    int iswhexnumber (wint_t wc);
    int iswideogram (wint_t wc);
    int iswlower (wint_t wc);
    int iswnumber (wint_t wc);
    int iswphonogram (wint_t wc);
    int iswprint (wint_t wc);
    int iswpunct (wint_t wc);
    int iswrune (wint_t wc);
    int iswspace (wint_t wc);
    int iswspecial (wint_t wc);
    int iswupper (wint_t wc);
    int iswxdigit (wint_t wc);
     

    DESCRIPTION

    The above functions are character classification utility functions, for use with wide characters Vt ( wchar_t or Vt wint_t ) . See the description for the similarly-named single byte classification functions (like isalnum(3)), for details.  

    RETURN VALUES

    The functions return zero if the character tests false and return non-zero if the character tests true.  

    SEE ALSO

    isalnum(3), isalpha(3), isascii(3), isblank(3), iscntrl(3), isdigit(3), isgraph(3), ishexnumber(3), isideogram(3), islower(3), isnumber(3), isphonogram(3), isprint(3), ispunct(3), isrune(3), isspace(3), isspecial(3), isupper(3), isxdigit(3), wctype(3)  

    STANDARDS

    These functions conform to St -p1003.1-2001 , except iswascii (,);
    iswhexnumber (,);
    iswideogram (,);
    iswnumber (,);
    iswphonogram (,);
    iswrune ();
    and iswspecial (,);
    which are Fx extensions.  

    CAVEATS

    The result of these functions is undefined unless the argument is WEOF or a valid Vt wchar_t value for the current locale.
