Sockets NetworkStream. tcpSocket->ExclusiveAddressUse = true; // The socket will linger for 10 seconds after // Socket. so the stream writes data to an internal buffer with a fixed size, a socket or database. How can I empty the buffer if they continue to fill it?. This means that when a client socket's thread invokes a read operation, it blocks the server until the data is available. If I'm right, they go in a buffer (FIFO) and everytime I listen the socket, I read the oldest one, right? Is there a way to delete the buffer and everytime read the next message? I want to ignore all the oldest messages Another problem is that I've like a tons of message every seconds. The problem is, that the File Data Buffer (FDB) isn't cleared, that is the second message is just added to the first message. The maximum congestion window is related to the amount of buffer space that the kernel allocates for each socket. The implementation of UDP sockets is a lot simpler. Care should be taken if explicitly setting this value. Crouzet Curtis Industries Finder Relays, Inc. to somehow flush the receive buffer associated to my socket, but I haven't found any way to do so.

In this example, you will use your Ethernet Shield and your Arduino to send and receive text strings via the UDP protocol (Universal Datagram Packet). 1 - concerning re-handshaking I wonder in which case this could happen ? I have developed both the client and the server side; there will only be one request per connection from the client side but the server will send back a lot of data up to the client and this can be quite long, can a re-handshake occured realy at any time ?. Typed array views. Specific details depends on the way you use sockets, but basically this is your software responsibility to match what the server send and the client receive (or the other way around).
