Name

cyg_mdns_init — Initialise mDNS Responder

Synopsis

#include <mdns.h>

cyg_bool cyg_mdns_init(void);

Description

This initialises the common mDNS support. It will normally be called from the application shortly after lwIP initialisation, and performs the basic “start-of-day” initialisation.

Note

	Note
All of the required lwIP network interfaces should have been added (normally via a call to the `init_all_network_interfaces()`) prior to initialising the mDNS Responder. If network interfaces are subsequently removed then the mDNS daemon should be disabled and re-enabled with the functions `cyg_mdns_disable()` and `cyg_mdns_enable()` to ensure the correct interface configurations are used. If network interfaces are subsequently added, it is sufficient to call solely `cyg_mdns_enable()` so that it configures the new interface for mDNS requests.

Once initialised, it is possible to register services with cyg_mdns_service_register(), and then allow the mDNS responder to respond to incoming requests with cyg_mdns_enable().

Return value

Boolean true if the mDNS sub-system has initialised OK, or false on failure.
