Converts an uppercase wide character to a lowercase wide character.
Standard C Library (libc.a)
#include <wchar.h>
wint_t towlower ( WC) wint_t WC;
wint_t towlower_l( WC,Locale) wint_t WC; locale_t Locale;
The towlower subroutine converts the uppercase wide character specified by the WC parameter into the corresponding lowercase wide character. The LC_CTYPE category affects the behavior of the towlower subroutine.
The towlower_l subroutine is same as the towlower routine, except that the locale data used is from the locale represented by Locale.
| Item | Description |
|---|---|
| WC | Specifies the wide character to convert to lowercase. |
| Locale | Specifies the locale in which character has to be converted. |
If the WC parameter contains an uppercase wide character that has a corresponding lowercase wide character, that wide character is returned. Otherwise, the WC parameter is returned unchanged.
