C#, tcp client..
- NetworkStream stream = client.GetStream();
- byte[] buffer = new byte[640 * 480];
- int read, total = 0;
-
- // Blocking Read here
- while ((read = stream.Read(buffer, total, 1000)) != 0)
- {
- total += read;
- }

NetworkStream class 提供的Methods 有 Read 及 ReadAsync 兩種,
當中的Read是synchronous的, 所以 comment 是blocking read.

can check NetworkStream.DataAvailable before read
which can avoid blocking
