definiert in Header `<cwchar>`

`wchar_t* wmemcpy( wchar_t* dest, const wchar_t* src, std::size_t count );`

Kopien count breite Zeichen aus dem Objekt, auf das src auf das Objekt, auf das dest. Wenn die Objekte überlappen, ist das Verhalten undefiniert. Wenn die Objekte nicht trivial kopierbar (Skalare, Arrays, C-kompatible Strukturen), ist das Verhalten undefiniert .

Original:

Copies count wide characters from the object pointed to by src to the object pointed to by dest. If the objects overlap, the behavior is undefined. If the objects are not trivially copyable (scalars, arrays, C-compatible structs), the behavior is undefined.
