| <p><code>AcceptEx()</code> is a Microsoft WinSock v2 API that provides |
| some performance improvements over the use of the BSD style |
| <code>accept()</code> API in certain circumstances. Some popular Windows |
| products, typically virus scanning or virtual private network |
| packages, have bugs that interfere with the proper operation of |
| <code>AcceptEx()</code>. If you encounter an error condition like:</p> |
| |
| <div class="example"><p><code> |
| [error] (730038)An operation was attempted on something that is |
| not a socket.: winnt_accept: AcceptEx failed. Attempting to recover. |
| </code></p></div> |
| |
| <p>you should use this directive to disable the use of |
| <code>AcceptEx()</code>.</p> |
