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.
