C in a Nutshell

Name

towupper

Synopsis

Converts a lowercase wide character to uppercase

#include <wctype.h>
wint_ttowupper( wint_t wc );

The towupper() function is like toupper() in all respects, except that it operates on wide characters. An uppercase wide character is one for which iswupper() returns true in the current locale; a lowercase wide character is one for which iswlower() returns true.
