Defined in header <cwchar>
wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count );
Copias ch carácter ancho en cada uno de los primeros count caracteres anchos del objeto apuntado por dest. Si el objeto no es trivial-copiable (por ejemplo, escalar, matriz o una estructura C-compatible), el comportamiento no está definido. Si los puntos dest+size+1 fuera del objeto, el comportamiento no está definido .
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.
