FUNCTION
<<towupper>>, <<towupper_l>>---translate wide characters to uppercase
INDEX
towupper
INDEX
towupper_l
SYNOPSIS
#include <wctype.h>
wint_t towupper(wint_t <[c]>);
#include <wctype.h>
wint_t towupper_l(wint_t <[c]>, locale_t <[locale]>);
DESCRIPTION
<<towupper>> is a function which converts lowercase wide characters to
uppercase, leaving all other characters unchanged.
<<towupper_l>> is like <<towupper>> but performs the function 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
<<towupper>>, <<towupper_l>> return the uppercase equivalent of <[c]> when it is a
lowercase wide character, otherwise, it returns the input character.
PORTABILITY
<<towupper>> is C99.
<<towupper_l>> is POSIX-1.2008.
No supporting OS subroutines are required.
