iswalnum
ISWALNUM(3) Linux Programmer's Manual ISWALNUM(3)NAME
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(3) function. It tests whether wc is a wide character 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-char-
acter 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 nonzero if wc is a wide character belonging to the wide-character class "alnum". Otherwise it returns
zero.
CONFORMING TO
C99.
NOTES
The behavior of iswalnum() depends on the LC_CTYPE category of the current locale.
