|
| -<p>On a successful return, the address of the peer

| -<h5>Description</h5>
|
| -<p>Once a UDT socket is in listening state, it accepts new connections and maintains the pending connections in a queue. An <strong>accept</strong> call retrieves
|
| -the first connection in the queue, removes it from the queue, and returns the associate socket descriptor. </p>
|
| -<p>If there is no connections in the queue when <strong>accept</strong> is called, a blocking socket will wait until a new connection is set up, whereas a
|
| -non-blocking socket will return immediately with an error.</p>
|
| -<p>The accepted sockets will inherit all proper attributes from the listening socket.</p>
