34<td>Process was successful.</td>
35        </tr>
36        <tr>
37<th>ResultProtocolFailedErr</th>
38<td>Indicates that an error occurred due to SSL protocol failure. (This can occur if client certificate authentication fails on the server side, for example.) To reconnect, first call the <a href="../../../nn/ssl/Connection/Overview.html"><CODE>Connection</CODE></a> object's <a href="../../../nn/ssl/Finalize.html"><CODE>Finalize</CODE></a> function, and then call <a href="../../../nn/ssl/Connection/Initialize.html"><CODE>Initialize</CODE></a> again.</td>
39        </tr>
40        <tr>
41<th>ResultWantRead</th>
42<td>Indicates, when an asynchronous socket was being used, that the receive function (<CODE><a href="../../../nn/socket/Read.html">nn::socket::Read</a></CODE>, etc.) returned without waiting for the operation to complete. Please try again.</td>
43        </tr>

45<th>ResultWantWrite</th>
46<td>Indicates, when an asynchronous socket was being used, that the receive function (<CODE><a href="../../../nn/socket/Read.html">nn::socket::Write</a></CODE>, etc.) returned without waiting for the operation to complete. Please try again.</td>
47        </tr>
48        <tr>
49<th>ResultSystemCallErr</th>
50<td>Indicates that the library function being used internally (mostly the socket functions) returned an unexpected error. (There was an abnormal response from the server, etc.) To reconnect, first call the <a href="../../../nn/ssl/Connection/Overview.html"><CODE>Connection</CODE></a> object's <a href="../../../nn/ssl/Finalize.html"><CODE>Finalize</CODE></a> function, and then call <a href="../../../nn/ssl/Connection/Initialize.html"><CODE>Initialize</CODE></a> again.</td>
51        </tr>
52        <tr>
53<th>ResultSocketZeroReturn</th>
54<td>Indicates that the socket read/write function returned 0 (in other words, indicates that communication was aborted). To reconnect, first call the <a href="../../../nn/ssl/Connection/Overview.html"><CODE>Connection</CODE></a> object's <a href="../../../nn/ssl/Finalize.html"><CODE>Finalize</CODE></a> function, and then call <a href="../../../nn/ssl/Connection/Initialize.html"><CODE>Initialize</CODE></a> again.</td>
55        </tr>
56        <tr>
57<th>ResultWantConnect</th>
58<td>Indicates, when an asynchronous socket is being used, that the connection still has not completed. Please try again.</td>
59        </tr>
60        <tr>
61<th>ResultVerifyCertErr</th>
62<td>Indicates that certificate verification failed. (When this is returned, it is possible to get the cause of the failure with the <CODE>nn::ssl::Connection::GetCertVerifyErrors</CODE> function.) To reconnect, first call the <a href="../../../nn/ssl/Connection/Overview.html"><CODE>Connection</CODE></a> object's <a href="../../../nn/ssl/Finalize.html"><CODE>Finalize</CODE></a> function, and then call <a href="../../../nn/ssl/Connection/Initialize.html"><CODE>Initialize</CODE></a> again.</td>
63        </tr>
64        <tr>
65<th>ResultIpcSessionErr</th>
66<td>Error indicating an uninitialized connection. No action performed because the <CODE>Connection</CODE> object has not been initialized by a successful call of <a href="../../../nn/ssl/Connection/Initialize.html"><CODE>Initialize</CODE></a>.</td>
67        </tr>
68        <tr>
69<th>ResultNotInitializedErr</th>
70<td>Error indicating that the library is not initialized. None of the functions in this library can be run without first running <a href="../../../nn/ssl/Initialize.html"><CODE>nn::ssl::Initialize</CODE></a>.</td>
71        </tr>
72        <tr>
