Defined in header <cwchar>
wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count );
Copie ch caratteri larghi in ciascuno dei primi count caratteri estesi dell'oggetto puntato da dest. Se l'oggetto non è banalmente-copiabile (ad esempio, scalare, un array o un C-compatibile struct), il comportamento è indefinito. Se i punti dest+size+1 fuori l'oggetto, il comportamento non è definito.
Original:
Copies wide character ch into each of the first count wide characters of the object pointed to by dest. If the object is not trivially-copyable (e.g., scalar, array, or a C-compatible struct), the behavior is undefined. If dest+size+1 points outside the object, the behavior is undefined.
