NAME    [Toc]    [Back]

       iswxdigit - test for hexadecimal digit wide character

SYNOPSIS    [Toc]    [Back]

       #include <wctype.h>

       int iswxdigit (wint_t wc);

DESCRIPTION    [Toc]    [Back]

       The iswxdigit function is the wide-character equivalent of the isxdigit
       function. It tests whether wc is a wide character belonging 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 character
 class "xdigit" is disjoint from the wide character class "cntrl".

       Being a subclass of the wide character class "graph", the wide  character
  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  character
 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    [Toc]    [Back]

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

NOTES    [Toc]    [Back]

       The behaviour of iswxdigit depends on the LC_CTYPE category of the current
 locale.
