of the viewer on the workstation. If the viewer is installed this function
|

will return CWB_OK. If the viewer is not available, the function will return
|
||
|
|
CWB_NO_VIEWER and the errorHandle parameter (if provided) will contain an
|

|
|
appropriate error message. Using this function, applications can check for

|
viewer support without calling the <span class="apiname">cwbOBJ_DisplaySplF()</span> API.</p>
