getDestinationAddress()

virtual const Inet4Address & nidas::util::Inet4PacketInfo::getDestinationAddress ( ) const

inlinevirtual

The destination address of the packet.

For a received unicast packet it will be the address of the local interface. Or the destination address could be a multicast address or a broadcast address.

getFlags()

virtual int nidas::util::Inet4PacketInfo::getFlags ( ) const

inlinevirtual

The flags on the received packet.

See "man 7 ip". It can contain several flags: MSG_EOR, MSG_TRUNC, MSG_CTRUNC, MSG_OOB, MSG_ERRQUEUE.

References _flags.

getInterface()

virtual const Inet4NetworkInterface & nidas::util::Inet4PacketInfo::getInterface ( ) const

inlinevirtual

The interface that the packet was received on.

getLocalAddress()

virtual Inet4Address nidas::util::Inet4PacketInfo::getLocalAddress ( ) const

inlinevirtual

The local address of the packet.

For a received packet, it is the address of the local interface that the packet was received on.
