    Command:

    iswxdigit

    
    
    

    SYNOPSIS

           #include <wctype.h>
    
           int iswxdigit(wint_t wc);
    
    
    

    DESCRIPTION

           The  iswxdigit()  function  is  the  wide-character  equivalent  of the
           isxdigit(3) function.  It tests whether wc is a wide character  belong-
           ing to the wide-character class "xdigit".
    
           The  wide-character  class "xdigit" is a subclass of the wide-character
           class "alnum", and therefore also  a  subclass  of  the  wide-character
           class "graph" and of the wide-character class "print".
    
           Being  a subclass of the wide-character class "print", the wide-charac-
           ter class "xdigit" is disjoint from the wide-character class "cntrl".
    
           Being a subclass of the wide-character class "graph", the  wide-charac-
           ter  class  "xdigit"  is disjoint from the wide-character class "space"
           and its subclass "blank".
    
           Being a subclass of the wide-character class "alnum", the  wide-charac-
           ter class "xdigit" is disjoint from the wide-character class "punct".
    
           The  wide-character class "xdigit" always contains at least the letters
           'A' to 'F', 'a' to 'f' and the digits '0' to '9'.
    
    
    

    RETURN VALUE

           The iswxdigit() function returns nonzero if  wc  is  a  wide  character
           belonging  to  the wide-character class "xdigit".  Otherwise it returns
           zero.

    NOTES

           The behavior of iswxdigit() depends on the  LC_CTYPE  category  of  the
           current locale.
