void* memmove( void* dest, const void* src, std::size_t count );
Копии count символов из объекта, на который указывает src на объект, на который указывает dest. Объекты могут перекрываться: копирование происходит, как если бы персонажи были скопированы во временный массив символов, а затем персонажи были скопированы из массива dest. Если объекты не тривиально копируемой (скаляры, массивы, C-стиле структуры), поведение не определено.
Original:
Copies count characters from the object pointed to by src to the object pointed to by dest. The objects may overlap: copying takes place as if the characters were copied to a temporary character array and then the characters were copied from the array to dest. If the objects are not trivially-copyable (scalars, arrays, C-style structs), the behavior is undefined.
