## Constructor & Destructor Documentation

KNetwork::KMulticastSocketImpl::KMulticastSocketImpl | ( | const KSocketBase * | = `0L` | ) |

| Constructor.

virtual KNetwork::KMulticastSocketImpl::~KMulticastSocketImpl | ( |  | ) | `[virtual]`

| Destructor.

## Member Function Documentation

virtual int KNetwork::KMulticastSocketImpl::capabilities | ( |  | ) | const`[virtual]`

| Sets our capabilities. Reimplemented from KNetwork::KSocketDevice.

virtual bool KNetwork::KMulticastSocketImpl::create | ( | int | family,
|  | int | type,
|  | int | protocol
| ) | `[virtual]`

| Overrides the socket creation. Reimplemented from KNetwork::KSocketDevice.

virtual bool KNetwork::KMulticastSocketImpl::connect | ( | const KResolverEntry & | address | ) | `[virtual]`

| Overrides connection. Multicast sockets may not connect. Reimplemented from KNetwork::KSocketDevice.

virtual int KNetwork::KMulticastSocketImpl::timeToLive | ( |  | ) | const`[virtual]`

| Retrieves the time-to-live/hop count value on multicast packets being sent.

virtual bool KNetwork::KMulticastSocketImpl::setTimeToLive | ( | int | ttl | ) | `[virtual]`

  | Sets the time-to-live/hop count for outgoing multicast packets. Parameters:
  | ttl | the hop count, from 0 to 255
Returns: true if setting the value was successful.

virtual bool KNetwork::KMulticastSocketImpl::multicastLoop | ( |  | ) | const`[virtual]`

| Retrieves the flag indicating if sent packets will be echoed back to sender.

virtual bool KNetwork::KMulticastSocketImpl::setMulticastLoop | ( | bool | enable | ) | `[virtual]`

  | Sets the flag indicating the loopback of packets to the sender. Parameters:
  | enable | if true, will echo back
Returns: true if setting the value was successful.

virtual KNetworkInterface KNetwork::KMulticastSocketImpl::networkInterface | ( |  | ) | `[virtual]`

| Retrieves the network interface this socket is associated to.

virtual bool KNetwork::KMulticastSocketImpl::setNetworkInterface | ( | const KNetworkInterface & | iface | ) | `[virtual]`

  | Sets the network interface on which this socket should work. Parameters:
  | iface | the interface to associate with
Returns: true if setting the value was successful.

virtual bool KNetwork::KMulticastSocketImpl::joinGroup | ( | const KSocketAddress & | group | ) | `[virtual]`

  | Joins a multicast group. The group to be joined is identified by the `group` parameter. Parameters:
  | group | the multicast group to join
Returns: true on success

virtual bool KNetwork::KMulticastSocketImpl::joinGroup | ( | const KSocketAddress & | group,
|  | const KNetworkInterface & | iface
| ) | `[virtual]`

| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Joins a multicast group. This function also specifies the network interface to be used.

virtual bool KNetwork::KMulticastSocketImpl::leaveGroup | ( | const KSocketAddress & | group | ) | `[virtual]`

  | Leaves a multicast group. The group being left is given by its address in the `group` parameter. Parameters:
  | group | the group to leave
Returns: true on successful leaving the group

virtual bool KNetwork::KMulticastSocketImpl::leaveGroup | ( | const KSocketAddress & | group,
|  | const KNetworkInterface & | iface
| ) | `[virtual]`

| This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts. Leaves a multicast group.
