| 11 | SYNOPSIS |
|---|
| 12 | #include <wctype.h> |
|---|
| 13 | int iswupper(wint_t <[c]>); |
|---|
| 14 | |
|---|
| 15 | #include <wctype.h> |
|---|
| 16 | int iswupper_l(wint_t <[c]>, locale_t <[locale]>); |
|---|
| 17 | |
|---|
| 18 | DESCRIPTION |
|---|
| 19 | <<iswupper>> is a function which classifies wide-character values that |
|---|
| 20 | have uppercase translations. |
|---|
| 21 | |
|---|
| 22 | <<iswupper_l>> is like <<iswupper>> but performs the check based on the |
|---|
| 23 | locale specified by the locale object locale. If <[locale]> is |
|---|
| 24 | LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined. |
|---|
| 25 | |
|---|
| 26 | RETURNS |
|---|
| 27 | <<iswupper>>, <<iswupper_l>> return non-zero if <[c]> is a uppercase wide character. |
|---|
| 28 | |
|---|
| 29 | PORTABILITY |
|---|
| 30 | <<iswupper>> is C99. |
|---|
| 31 | <<iswupper_l>> is POSIX-1.2008. |
|---|
| 32 | |
|---|
| 33 | No supporting OS subroutines are required. |
