title: WSABUF structure used in several wsasend
body: <p>I am aware that i should provide each Wsasend/recv operation unique OVERLAPPED structure or buffer and keep them valid until GQCS notification. But i need a little clarification about WSABUF structure, should it be unique too, or i can reuse it like this:</p>
  
  <pre><code>....
  WSABUF bufftoSend;
  
  bufftoSend.buf=buffer1;
  bufftoSend.len=40;
  WSASend(Socket, &amp;bufftoSend, 1,..., NULL);
  
  bufftoSend.buf=buffer2;
  bufftoSend.len=20;
  WSASend(Socket, &amp;bufftoSend, 1,..., NULL);
  
  bufftoSend.buf=buffer3;
  bufftoSend.len=30;
  WSASend(Socket, &amp;bufftoSend, 1,..., NULL);
  ....
  </code></pre>
  
  <p>?</p>
  
  <p>thanks for help.</p>
