-<h3><font color="#000080">UDT Socket Structures</font></h3>

-<p>The structures used in UDT API are listed in the table below:</p>

-<table width="100%" border="1" cellpadding="1" cellspacing="0" bordercolor="#CCCCCC">

- <tr>

- <td width="17%" class="table_headline"><strong>Structures</strong></td>

- <td>UDT performance statistics and protocol parameters</td>

- </tr>

-</table>

-<h5><a name="1" id="1"></a>UDTSOCKET</h5>

-<p>This is used as the descriptor of a UDT socket. Its internal is not exposed to application and subject to future changes.</p>

-<h5><a name="2" id="2"></a>ERRORINFO</h5>

-<p>The ERRORINFO structure contains the specific information of a UDT error. It has two helper functions to let applications know an integral error code and a piece of text information.</p>

-<table width="100%" border="1" cellpadding="1" cellspacing="0" bordercolor="#CCCCCC">

- <tr>

- <td width="30%" class="table_headline"><strong>Functions</strong></td>

- <td width="70%" class="table_headline"><strong>Comments</strong></td>

- </tr>

- <tr>

- <td>int getErrorCode()</td>

- <td>read the UDT error code</td>

- </tr>

- <tr>

- <td>const char* getErrorMessage()</td>

- <td>read the text information about the error.</td>

- </tr>

- <tr>

- <td>void clear()</td>

- <td>clear the error information (set to SUCCESS).</td>

- </tr>

-</table>

-<h5><a name="3" id="3"></a>UDSET</h5>

-<p>The UDSET structure is used with <a href="select.htm"><strong>select</strong></a> call to access multiple UDT descriptors.</p>

-<p>Four macros are defined on the UDSET structure to processing a UDT socket set. They are very similar to the fd_set structure and macros in traditional standard socket API.</p>

-<h5><a name="4" id="4"></a>TRACEINFO</h5>

-<p>The TRACEINFO structure stores the performance trace information. Its member attributes can be read directly by applications.</p>
