<h5>Return Value</h5>
<p>On success, <strong>getlasterror</strong> returns 0 and the local address information is stored in <i>name</i>; otherwise it returns UDT::ERROR and the specific error information can be

<h5>Description</h5>
<p>The <strong>getsockname</strong> retrieves the local address associated with the socket. The UDT socket must be bound explicitly (via <strong>bind</strong>) or implicitly (via
<strong>connect</strong>), otherwise this method will fail because there is no meaningful address bound to the socket.</p>
