NAME


       iswxdigit - test for hexadecimal digit wide character

 

SYNOPSIS


       #include 

       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 non-zero if wc  is  a  wide  character
       belonging  to  the wide-character class "xdigit".  Otherwise it returns
       zero.

 

CONFORMING TO


       C99.

 

NOTES


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