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"
