Because I Know the order in which they connect. how can i be certain that when i call sock[0]->SendBuf No other can read(mainly) or write at the same time. It is abvious that they are all using the same port. Is Their any way of Doing Such A Thing? The Sockets Are connected as follows. Server----Client sock[0]<->sock[0] sock[1]<->sock[2] sock[2]<->sock[1] sock[3]<->sock[3] even though sock[1] sends only and sock[2] receives only sometimes their is confusion when sock[1]->sendbuf is called from both the server and the client and they stuck. i made that way believing that they would be independent but even now they aren't. Do you know what i can do>
