bool P2PApplicationBase::sendP2PAck (  )  [protected, inherited]

Send an ACK message if this is needed.

This method called each time a P2P payload is fully received (such as an SLP message). The ACK system turns the P2P communication into a stop-and-wait protocol. The other client waits until it receives an ACK or error before it continues with the next step.

This function is mostly used by the derived P2PApplication class. It calls sendP2PAck() when a SLP message is properly received.

Whether an ack had to be sent.
