icpIncomingConn

Comm::ConnectionPointer icpIncomingConn = nullptr

Definition at line 99 of file icp_v2.cc.

Referenced by comm_poll_udp_incoming(), comm_select_udp_incoming(), fdIsUdpListen(), fdIsUdpListener(), icpConnectionShutdown(), icpOpenPorts(), mcastJoinGroups(), and neighbors_init().

icpOutgoingConn

Comm::ConnectionPointer icpOutgoingConn = nullptr

Referenced by icpClosePorts(), icpConnectionShutdown(), icpHandleUdp(), icpIncomingConnectionOpened(), and icpOpenPorts().

IcpQueueHead

DelayedUdpSend* IcpQueueHead = nullptr

static

IcpQueueHead is global so comm_incoming() knows whether or not to call icpUdpSendQueue.
