RedHat 9 (Linux i386) - man page for iswalpha (redhat section 3)

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 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 non-zero if wc is a wide character  belonging  to	the  wide
       character class "alpha". Otherwise it returns zero.

CONFORMING TO
       ISO/ANSI C, UNIX98

SEE ALSO
       isalpha(3), iswctype(3)

NOTES
       The behaviour of iswalpha depends on the LC_CTYPE category of the current locale.
