DESCRIPTION
This function is invoked while the app is being loaded. All Modules must provide this
function. Ensure to retain the same name and parameters for this function.
In here, the module must verify the ClassID and then invoke the AEEApplet_New() function
that has been provided in AEEAppGen.c.
After invoking AEEApplet_New(), this function can do app specific initialization. In this
example, a generic structure is provided so that app developers need not change app specific
initialization section every time except for a call to IDisplay_InitAppData().
This is done as follows: InitAppData() is called to initialize AppletData
instance. It is app developers responsibility to fill-in app data initialization
code of InitAppData(). App developer is also responsible to release memory
allocated for data contained in AppletData -- this can be done in
IDisplay_FreeAppData().
PROTOTYPE:
int AEEClsCreateInstance(AEECLSID ClsId,IShell * pIShell,IModule * po,void ** ppObj)
PARAMETERS:
clsID: [in]: Specifies the ClassID of the applet which is being loaded
pIShell: [in]: Contains pointer to the IShell object.
pIModule: pin]: Contains pointer to the IModule object to the current module to which
this app belongs
ppObj: [out]: On return, *ppObj must point to a valid IApplet structure. Allocation
of memory for this structure and initializing the base data members is done by AEEApplet_New().
DEPENDENCIES
none
RETURN VALUE
AEE_SUCCESS: If the app needs to be loaded and if AEEApplet_New() invocation was
successful
EFAILED: If the app does not need to be loaded or if errors occurred in
AEEApplet_New(). If this function returns FALSE, the app will not be loaded.
SIDE EFFECTS
none

PARAMETERS:
pi: Pointer to the AEEApplet structure. This structure contains information specific
to this applet. It was initialized during the AEEClsCreateInstance() function.
