title: Difference between read_some/write_some and receive/send?
body: <p>I am beginning to work with Boost Asio's TCP sockets.  What is the difference between <a href="http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/basic_stream_socket/read_some.html"><code>read_some</code></a> and <a href="http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/basic_stream_socket/receive.html"><code>receive</code></a> and what is the difference between <a href="http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/basic_stream_socket/write_some.html"><code>write_some</code></a> and <a href="http://www.boost.org/doc/libs/1_44_0/doc/html/boost_asio/reference/basic_stream_socket/send.html"><code>send</code></a>?  Thanks!</p>
