Parameters

  netif | the netif for which to set the struct autoip
  autoip | (uninitialised) autoip struct allocated by the application

## ◆ autoip_start()

err_t autoip_start | ( | struct netif * | netif | ) |

Start AutoIP client

Parameters

  netif | network interface on which start the AutoIP client

## ◆ autoip_stop()
