<name>Win32DisableAcceptEx</name>
<description>Use accept() rather than AcceptEx() to accept network connections</description>
<syntax>Win32DisableAcceptEx</syntax>
<default>AcceptEx() is enabled by default. Use this directive to disable use of
    AcceptEx()</default>
<contextlist><context>server config</context></contextlist>
<compatibility>Available in Version 2.0.49 and later</compatibility>

<usage>
    <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>

    <example>
        [error] (730038)An operation was attempted on something that is
        not a socket.: winnt_accept: AcceptEx failed. Attempting to recover.
    </example>

    <p>you should use this directive to disable the use of
    <code>AcceptEx()</code>.</p>
