iswalpha
ISWALPHA(3) Linux Programmer's Manual ISWALPHA(3)
NAME
iswalpha - test for alphabetic wide character
SYNOPSIS
#include <wctype.h>
int iswalpha(wint_t wc);
DESCRIPTION
The iswalpha() function is the wide-character equivalent of the isalpha(3) function. It tests whether wc is a wide character belonging to
the wide-character class "alpha".
The wide-character class "alpha" 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 "alpha" is disjoint from the wide-character class "cntrl".
Being a subclass of the wide-character class "graph", the wide-character class "alpha" 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 "alpha" is disjoint from the wide-character class "punct".
The wide-character class "alpha" is disjoint from the wide-character class "digit".
The wide-character class "alpha" contains the wide-character classes "upper" and "lower".
The wide-character class "alpha" always contains at least the letters 'A' to 'Z' and 'a' to 'z'.
RETURN VALUE
The iswalpha() function returns nonzero if wc is a wide character belonging to the wide-character class "alpha". Otherwise, it returns
zero.
ATTRIBUTES
For an explanation of the terms used in this section, see attributes(7).

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99.
NOTES
The behavior of iswalpha() depends on the LC_CTYPE category of the current locale.
