<P>This is what we do to create an acceptor from the ACE template:</P>
<UL>
<PRE>
1. #include "ace/Acceptor.h"
2. #include "ace/SOCK_Acceptor.h"
3. typedef ACE_Acceptor <Logging_Handler, ACE_SOCK_ACCEPTOR> Logging_Acceptor;
</PRE>
</UL>
<P>
<HR></P>
<P>Now, if you think that was difficult, you may as well give up now.</P>
<OL>
<LI>The <I>Acceptor</I> header file defines the template we're about to
use. This is a totally generic object where all of the hard work as already
been done.</LI>
<LI>Because we want to accept connections on an <I>ACE_SOCK_Stream</I>,
we have to pull in this header. It provides the API details that we will
need.</LI>
<LI>Finally, create a <I>Logging_Acceptor</I> object based on the <I>ACE_Acceptor</I>
template. The first parameter <I>Logging_Handler</I> is an object we will
develop on the next page. This object will be created by the template-generated
code whenever a new connection request is accepted. The second parameter
tells the template what kind of acceptor to create. It is most important
that the first-parameter object and the second parameter be consistent
in the connetion types used.</LI>
</OL>
<P>Obviously we're doing things a bit out of order here: <I>main</I> won't
be happy until it knows what a <I>Logging_Acceptor</I> is and the acceptor
won't be happy until it knows what a <I>Logging_Handler</I> is. The next
page pulls in this last definition for us and after that we tie it all
together.</P>
