<p>Use the QzhtRtvTCMHostDesc API to retrieve information from host descriptions
associated with triggered cache manager servers. The API is a callable service
implemented as an ILE entry point within the QZHTINCONF *SRVPGM in the QTCM
*LIB. </p>
<p>The QTCM/H(QZHTINCONF) header file includes ILE C prototypes for this API.</p>
