<p>The Generate Clustered Hash Table Key (QcstGenerateCHTKey) API returns a universally unique key
that can be used to store an entry into the clustered hash table.</p>
<br>
<h3>Restrictions:</h3>
<ul>
<li>A connection must have been established with the clustered hash table
server.</li>
<li>When this API is called, the clustered hash table server must be active
on the requesting node.</li>
<li>This API must be run under the same job that issued the <a href="clchtconnect.htm">Connect Clustered Hash Table (QcstConnectCHT)</a> API.
</ul>
<h3>Authorities and Locks</h3>
<br>
<h3>Required Parameter Group</h3>
<dl>
<dt><strong>Key</strong></dt>
<dd>OUTPUT; CHAR(*)
<p>The receiver variable that receives the generated key. The size of this
parameter must be at least equal to the length of key to generate
parameter.</p>
</dd>
<dt><strong>Length of key to generate</strong></dt>
<dd>INPUT; BINARY(4)
<p>The length of the key to be generated. This length must be equal to 16.</p>
</dd>
<dt><strong>Connection handle</strong></dt>
<dd>INPUT; CHAR(16)
<p>This is an active connection handle for the clustered hash table server.
It is obtained by calling the <a href="clchtconnect.htm">Connect Clustered Hash Table (QcstConnectCHT)</a> API.</p>
</dd>
<dt><strong>Error code</strong></dt>
<dd>I/O; CHAR(*)
<p>The structure in which to return error information. For the format of the
structure, see <a href="../apiref/error.htm#hdrerrcod">Error Code Parameter</a>.</p>
