void P2PApplicationBase::sendP2PMessage ( const QByteArray &  messageData,
int  flagField = 0,
P2PDataType  footerCode = P2P_TYPE_NEGOTIATION,
P2PMessageType  messageType = P2P_MSG_UNKNOWN 
) [protected, inherited]

Sends a complete P2P message payload.

It splits the data message into chunks which fit in the individual P2P messages.

If you need to send data, use sendData() instead. This method is stream based, and also takes care of state changes.

messageData The message payload to send.
flagField The value for the flag field in the P2P header.
footerCode The message footer, which is appended when the message is sent over the switchboard.
messageType The type of the message. This value is returned with gotAck().
