By default, advertises HTTP server (if enabled).

Additional insances can be added by user's application, example (for Apple HAP):

const struct mgos_dns_sd_txt_entry gizmo_txt[] = {
    {.key = "c#", .value = MG_MK_STR("1")},
    {.key = "ff", .value = MG_MK_STR("0")},
    {.key = "pv", .value = MG_MK_STR("1.0")},
    {.key = "id", .value = MG_MK_STR("11:22:33:44:55:66")},
    {.key = "md", .value = MG_MK_STR("Fancy Gizmo 9000")},
    {.key = "s#", .value = MG_MK_STR("1")},
    {.key = "sf", .value = MG_MK_STR("1")},
    {.key = "ci", .value = MG_MK_STR("8")},  // Switch
    {.key = NULL},
};
mgos_dns_sd_add_service_instance("gizmo9000", "_hap._tcp", 8080, gizmo_txt);

mgos_dns_sd_get_host_name

const char *mgos_dns_sd_get_host_name(void);

Return currently configure DNS-SD hostname.

mgos_dns_sd_add_service_instance

bool mgos_dns_sd_add_service_instance(
    const char *instance, const char *proto, int port,
    const struct mgos_dns_sd_txt_entry *txt_entries);

Add a service instance. If service instance already exists, its definition will be replaced. A record will be added automatically to point to the device. If txt_entries is not NULL, it must end with an entry with key=NULL.

Example (for Apple HAP):

const struct mgos_dns_sd_txt_entry gizmo_txt[] = { {.key = "c#", .value = MG_MK_STR("1")}, {.key = "ff", .value = MG_MK_STR("0")}, {.key = "pv", .value = MG_MK_STR("1.0")}, {.key = "id", .value = MG_MK_STR("11:22:33:44:55:66")}, {.key = "md", .value = MG_MK_STR("Fancy Gizmo 9000")}, {.key = "s#", .value = MG_MK_STR("1")}, {.key = "sf", .value = MG_MK_STR("1")}, {.key = "ci", .value = MG_MK_STR("8")}, // Switch {.key = NULL}, }; mgos_dns_sd_add_service_instance("gizmo9000", "_hap._tcp", 8080, gizmo_txt);

mgos_dns_sd_remove_service_instance

bool mgos_dns_sd_remove_service_instance(
    const char *instance, const char *proto, int port);

Stop advertising the specified instance.
