[QUOTE="georgius, post: 728805, member: 107951"] It works little bit different (as I know). IPTV_SOCKET_BUFFER_SIZE specifies size of buffer for socket (in other words, Windows create its internal buffer of this size and attach it to socket, you don't have access to this buffer). In this buffer are written packets received from network. When you call recvfrom() it returns only first packet received (not all packets received) and memory in buffer is marked as free. With non-blocking sockets you have to call recvfrom() until it doesn't return SOCKET_ERROR and then you have to check if WSAGetLastError() is WSAEWOULDBLOCK, which means that are no data. With blocking sockets you just call recvfrom(). It doesn't return while no data received - this approach makes another problem with unresponsible thread because is blocked with recvfrom(). If you look in my code you'll see that I call Sleep(10) only when no data received or there is not space in my buffer. [/QUOTE]
