towupper(), towupper_l -- convert wide character to uppercase

SYNOPSIS

#include <wctype.h>

wint_t towupper(wint_t wc);

wint_t towupper_l(wint_t wc, locale_t locale);

DESCRIPTION

The towupper() (and towupper_l()) function converts a lowercase letter to the corresponding uppercase letter. The call towupper(wc)is equivalent to:

towctrans(wc, wctrans("toupper"));

towctrans_l(wc, wctrans("toupper"), locale);

PARAMETERS

wc: Is a wide character code corresponding to a valid character in the current locale or the value of the macro WEOF.
locale: Is a locale_t perhaps returned by newlocale() or LC_GLOBAL_LOCALE or 0 for the current thread locale set with uselocale().

If the parameter is a wide character for which iswlower() (or iswlower_l()) is true and there is a corresponding wide character for which iswupper() (or iswupper_l()) is true, the towupper() (and towupper_l()) function returns the corresponding wide character. Otherwise, the parameter is returned unchanged.

CONFORMANCE

towupper() conforms to ANSI/ISO 9899-1990/AM 1-1995.
