Defined in header <cwchar>
wchar_t* wmemcpy( wchar_t* dest, const wchar_t* src, std::size_t count );
Cópias count caracteres de largura do objeto apontado por src ao objeto apontado por dest. Se os objetos se sobrepõem, o comportamento é indefinido. Se os objetos não são trivialmente copiável (escalares, matrizes C-estruturas compatíveis), o comportamento é indefinido.
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.
