|
|
a connection is made to the iSeries system. If no connection has been made yet
|

|
|
to this iSeries system
|
||
|
|
in the currently-active environment, this information will not be available,
|
||
|
|
and the error code CWB_NOT_CONNECTED will be returned. If you know that a
|
||
|
|
connection to the iSeries system recently was made successfully, it
|
||
|
|
is likely that the version and release levels returned are current. If you
|
||
|
|
want to make sure that the values are available and recently have been retrieved,
|
||
|
|
call <span class="apiname">cwbCO_Signon</span> or <span class="apiname">cwbCO_Connect</span> for
|
||
|
|
this system object first, then call <span class="apiname">cwbCO_GetHostVersionEx</span>.</p>
