| -<h5>Description</h5>
|
| -<p>The <strong>listen</strong> method lets a UDT socket enter listening state. The socket must call <strong>bind</strong> before a <strong>listen</strong> call. In addition, if the
|
| -socket is enable for rendezvous mode, neither <strong>listen</strong> nor <strong>accept</strong> can be used on the socket. A UDT socket can call <strong>listen</strong> more than once,
|
| -in which case only the first call is effective, while all subsequent calls will be ignored if the socket is already in listening state.</p>
