DESCRIPTION
|
|
<<iswupper>> is a function which classifies wide-character values that
|
|
have uppercase translations.
|
|
|
|
<<iswupper_l>> is like <<iswupper>> but performs the check based on the
|
|
locale specified by the locale object locale. If <[locale]> is
|
|
LC_GLOBAL_LOCALE or not a valid locale object, the behaviour is undefined.
|
|
|
|
RETURNS
|
|
<<iswupper>>, <<iswupper_l>> return non-zero if <[c]> is a uppercase wide character.
|
|
|
|
PORTABILITY
|
|
<<iswupper>> is C99.
|
|
<<iswupper_l>> is POSIX-1.2008.
|
|
|
|
No supporting OS subroutines are required.
