Hi, Elliott<br>
<br>
I&#39;m very sorry for that. Currently I&#39;m trapping in other work and couldn&#39;t finish the promised UDP porting work immediately. My SNMP library also want to work on SBCL/win32, but ...<br>
<br>
>From my view, the biggest issue for this work, is the implementation of WAIT-FOR-INPUT-INTERNAL for UDP usockets. On Windows, there&#39;s no &quot;select()&quot; UNIX system call, so we have to use &quot;WSAEventSelect&quot; instead. I have no idea if SBCL/win32 have correspond internal functions which could be called directly by usocket.<br>

<div><br></div><div>Since there seems to be no select-like functionality built into sbcl/win32, is the right approach to call WSAEventSelect with sb-alien? (I assume that cffi is to avoided.) I can try to work on this is the next couple of days if this is the right way to go.</div>
