Send a message on the message channel. The message is sent
asynchronously. The method does not wait for a response before
returning. It usually completes quickly because it only waits for
local TCP implementation to accept the bytes into its network data
buffer. However, this message could block briefly for longer
messages, and/or if the network data buffer is nearly full.
It could even block indefinitely if the remote site is slow
to read.

<a href="M_BerkeleyDB_DbChannel_SendRequest_1.htm">SendRequest(<span class="languageSpecificText"><span class="cpp">array<</span></span>DatabaseEntry<span class="languageSpecificText"><span class="cpp">></span><span class="cs">[]</span><span class="vb">()</span><span class="nu">[]</span></span>, UInt32)</a> instead of this method.
</p>
<p>
The sent message is received and handled at remote sites using a
message dispatch callback, which is configured using
<a href="P_BerkeleyDB_DatabaseEnvironment_RepMessageDispatch.htm">RepMessageDispatch</a>. Note that this
method may be used within the the message dispatch callback on the
remote site to send a reply or acknowledgement for messages that it
receives and is handling.
</p>
<p>
This method may be used on channels opened to any destination. See
<a href="M_BerkeleyDB_DatabaseEnvironment_RepMgrChannel.htm">RepMgrChannel(Int32)</a> for a list of
potential destinations.
