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.
