While receiving the data, it should be processed on a
mainQueue
operation
block. In this block, we will remove the header in the
pIntData
pointer vari-
able and get the
NetworkPacketCode
sent in the packet. In this code, we will
check the type of packet which is sent. Then we will parse the packet based on its
