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

NAME
       iswlower - test for lowercase wide character

SYNOPSIS
       #include <wctype.h>

       int iswlower(wint_t wc);

DESCRIPTION
       The  iswlower()	function is the wide-character equivalent of the islower(3) function.  It
       tests whether wc is a wide character belonging to the wide-character class "lower".

       The wide-character class "lower" is a subclass of the wide-character  class  "alpha",  and
       therefore also a subclass of the wide-character class "alnum", 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 "lower"  is
       disjoint from the wide-character class "cntrl".

       Being  a subclass of the wide-character class "graph", the wide-character class "lower" 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 "lower"  is
       disjoint from the wide-character class "punct".

       Being  a subclass of the wide-character class "alpha", the wide-character class "lower" is
       disjoint from the wide-character class "digit".

       The wide-character class "lower" contains at least those characters wc which are equal  to
       towlower(wc) and different from towupper(wc).

       The wide-character class "lower" always contains at least the letters 'a' to 'z'.

RETURN VALUE
       The  iswlower()	function returns nonzero if wc is a wide character belonging to the wide-
       character class "lower".  Otherwise it returns zero.

CONFORMING TO
       C99.

NOTES
       The behavior of iswlower() depends on the LC_CTYPE category of the current locale.

       This function is not very appropriate for dealing with Unicode characters, because Unicode
       knows about three cases: upper, lower and title case.
