iswlower

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

CONFORMING TO

       ISO/ANSI C, UNIX98

SEE ALSO

       islower(3), iswctype(3), towlower(3)

NOTES

       The behaviour 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.
