Overview
The current value is obtained with getSendBufferSize() and set with setSendBufferSize(int). SO_SNDBUF is used by the network implementation as a hint to size the underlying I/O buffers. Calling setSendBufferSize(int) is no guarantee that the implementation will use the value, so the application may want to verify the buffer size with getSendBufferSize().
