// Notes:
|
|
// The file Mgmt\Inc\DllSrc.cpp is not included in this file
|
|
// because the inclusion of that file requires that the library
|
|
// Mgmt\ClusCfg\Common\$(O)\Common.lib be linked with this DLL. Also,
|
|
// the header file Guids.h from Mgmt\ClusCfg\Inc will be needed.
|
|
// (DllSrc.cpp requires CFactorySrc.cpp which requires CITrackerSrc.cpp
|
|
// which requires InterfaceTableSrc.cpp which needs Guids.h)
|
|
//
|
|
// Since I didn't wan't to "reach across" to the ClusCfg directory (and
|
|
// since this DLL does not need class factories, interface tracking, etc.)
|
|
// ClusOCM has it's own Dll.cpp.
