ISWXDIGIT(3)               Linux Programmer's Manual              ISWXDIGIT(3)



NAME
       iswxdigit - test for hexadecimal digit wide character

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 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  sub-
       class 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
       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.
