<p>A transaction manager calls <strong>xa_complete()</strong> to wait for the
completion of an asynchronous operation. Asynchronous operations are not
supported by the DB2 UDB for iSeries resource manager. This function is
provided only for compliance with the X/Open XA Specification.</p>
<br>
<h3>Parameters</h3>
<dl>
<dt><strong>handle</strong></dt>
<dd>(Input) A pointer to an integer value returned by an XA function that had
TMASYNC specified.<br>
<br>
</dd>
<dt><strong>retval</strong></dt>
<dd>(Output) A pointer to the integer return value of the asynchronous
function.<br>
<br>
</dd>
<dt><strong>rmid</strong></dt>
<dd>(Input) An integer value that the transaction manager generated when
calling <strong>xa_open()</strong>. The rmid identifies the resource
manager.<br>
<br>
</dd>
<dt><strong>flags</strong></dt>
<dd>(Input) The follow are valid settings of <em>flags</em>.
<p><em>TMMULTIPLE:</em> 0x00400000L Test completion of any outstanding
asynchronous operation.</p>
<p><em>TMNOWAIT:</em> 0x10000000L Test for completion without blocking.</p>
<p><em>TMNOFLAGS:</em> 0x00000000L Use if no other flags are set.</p>
