Defined in header <cstring>
void* memmove( void* dest, const void* src, std::size_t count );
Copie count caratteri dall'oggetto puntato da src all'oggetto puntato da dest. Gli oggetti possono sovrapporsi: la copia avviene come se i personaggi sono stati copiati in una matrice di carattere temporaneo e quindi i caratteri sono stati copiati dalla matrice a dest. Se gli oggetti non sono banalmente-copiabile (scalari, array, struct di tipo C), il comportamento è indefinito.
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.
