SYNOPSIS
#include <wchar.h>
wint_t towlower (
wint_t wc);
PARAMETER
wc Specifies the wide character to convert.
DESCRIPTION
The towlower( ) function converts the uppercase wide character specified by the wc parameter
into the corresponding lowercase wide character. The behavior of the towlower( ) function is
affected by the LC_CTYPE category of the program’s locale. In a locale where case conversion
information is not defined, this function determines the case of characters according to the rules
of the C locale.
RETURN VALUES
If the wc parameter contains a uppercase wide character that has a corresponding lowercase wide
character, that wide character is returned. Otherwise, the wc parameter is returned unchanged.
