towupper, towupper_l - transliterate lower-case wide characters to upper-case
#include <wctype.h> wint_t towupper(wint_t wc);
wint_t towupper_l(wint_t wc, locale_t loc);
The function towupper() is the wide character equivalent of the function toupper(3C). It converts the lower-case wide character wc to the equivalent upper-case wide character, if one exists. If one does not exist, it returns wc unchanged.
The function towupper_l() is equivalent to the function towupper(), but instead of operating in the current locale, operates in the locale specified by loc.
On successful completion, towupper() and towupper_l() return the upper-case character that corresponds to the argument passed. Otherwise, they return the argument unchanged.
No errors are defined.
