## Detailed Description

MDNS responder implementation

## Macro Definition Documentation

## MDNS_PROBE_COUNT

#define MDNS_PROBE_COUNT 3

Probing & announcing defines

## MDNS_RESPONSE_DELAY_MAX

#define MDNS_RESPONSE_DELAY_MAX 120

Delayed response defines

## Function Documentation

## get_mdns_pcb()

struct udp_pcb * get_mdns_pcb | ( | void |  | ) |

Construction to access the mdns udp pcb.

Returns
  udp_pcb struct of mdns

## mdns_resp_register_name_result_cb()

void mdns_resp_register_name_result_cb | ( | mdns_name_result_cb_t | cb | ) |

Register a callback function that is called if probing is completed successfully or with a conflict.

## netif_mdns_data()

struct mdns_host * netif_mdns_data | ( | struct netif * | netif | ) |

Construction to make mdns struct accessible from mdns_out.c TODO: can we add the mdns struct to the netif like we do for dhcp, autoip,...? Then this is not needed any more.

Parameters

  netif | The network interface

Returns
  mdns struct
