Socket.joinMulticastGroup

bool joinMulticastGroup(gio.inet_address.InetAddress group, bool sourceSpecific, string iface = null)

Registers socket to receive multicast messages sent to group. socket must be a [gio.types.SocketType.Datagram] socket, and must have been bound to an appropriate interface and port with [gio.socket.Socket.bind].

If iface is null, the system will automatically pick an interface to bind to based on group.

If source_specific is true, source-specific multicast as defined in RFC 4604 is used. Note that on older platforms this may fail with a [gio.types.IOErrorEnum.NotSupported] error.

To bind to a given source-specific multicast address, use [gio.socket.Socket.joinMulticastGroupSsm] instead.

Parameters

`group`	a #GInetAddress specifying the group address to join.
`sourceSpecific`	true if source-specific multicast should be used
`iface`	Name of the interface to use, or null

Returns

true on success, false on error.

Throws

[ErrorWrap]
