Defined in header <cstring>
void* memmove( void* dest, const void* src, std::size_t count );
Copias count personajes del objeto apuntado por src al objeto apuntado por dest. Los objetos pueden superponerse: la copia se lleva a cabo como si los personajes se copiaron en una matriz de caracteres temporal y los personajes fueron copiados de la matriz a dest. Si los objetos no son trivialmente-copiable (escalares, arrays estilo C-estructuras), el comportamiento no está definido .
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.
