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.
