iswalnum - test for alphanumeric wide character
SYNOPSIS
#include <wctype.h>
int iswalnum (wint_t wc);
DESCRIPTION
The iswalnum function is the wide-character equivalent of
the isalnum function. It tests whether wc is a wide char
acter belonging to the wide character class "alnum".
The wide character class "alnum" is a subclass of the wide
character class "graph", and therefore also a subclass of
the wide character class "print".
Being a subclass of the wide character class "print", the
wide character class "alnum" is disjoint from the wide
character class "cntrl".
Being a subclass of the wide character class "graph", the
wide character class "alnum" is disjoint from the wide
character class "space" and its subclass "blank".
The wide character class "alnum" is disjoint from the wide
character class "punct".
The wide character class "alnum" is the union of the wide
character classes "alpha" and "digit". As such, it also
contains the wide character class "xdigit".
The wide character class "alnum" always contains at least
the letters 'A' to 'Z', 'a' to 'z' and the digits '0' to
'9'.
RETURN VALUE
The iswalnum function returns non-zero if wc is a wide
character belonging to the wide character class "alnum".
Otherwise it returns zero.
