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