If a <em><code class="parameter">link</code></em> resource is passed to
<span class="function"><strong>ingres_errno()</strong></span> it returns the last error recorded for
the link. If no link is passed, then <span class="function"><strong>ingres_errno()</strong></span>
returns the last error reported using the default link.

The function, <span class="function"><strong>ingres_errno()</strong></span>, should always be called
after executing a database query. Calling another function before
<span class="function"><strong>ingres_errno()</strong></span> is called will reset or change any
error code from the last Ingres function call.
