Does boost provide a portable way to create a system::error_code object based on the last error?&nbsp; I don&#39;t see an obvious way to do this via the documentation unless I&#39;m just overlooking it.&nbsp; There&#39;s lots of ways to create uninitialized error code objects, or error code objects initialized to a specific value, but I don&#39;t see an obvious portable way of determining &quot;why the last operation failed&quot;.<br>
<br>Anyone encountered this before?<br>
