<p>
This function is used to write data to the stream descriptor. The function
call will block until one or more bytes of the data has been written
successfully, or until an error occurs.

<p>
The write_some operation may not transmit all of the data to the peer.
Consider using the <a class="link" href="../../write.html" title="write"><code class="computeroutput"><span class="identifier">write</span></code></a> function if you need to
ensure that all data is written before the blocking operation completes.
