Defined in header <cwchar>
wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count );
Kopien Breitzeichen ch in jede der ersten count breite Zeichen des Objekts, auf das dest. Wenn das Objekt nicht trivial kopierbaren (zB Skalar, Array oder ein C-kompatiblen struct), ist das Verhalten undefiniert. Wenn dest+size+1 Punkte außerhalb des Objekts, ist das Verhalten undefiniert .
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.
