FUNCTION c_SampleCameraApp_CameraCBFunc
DESCRIPTION
This callback notifier function handles all callbacks from ICamera.
Depending on how complex your application this function may need to handle
several use cases. The most common uses are error handling, state
transistion, displaying frames, and monitoring status.
PROTOTYPE:
static void c_SampleCameraApp_CameraCBFunc(SampleCameraApp* pMe,
AEECameraNotify * pcn)
PARAMETERS:
pMe: Pointer to the applet data stucture
pcn: This pointer to a AEECameraNotify structure contains information about
the ICamera object.
DEPENDENCIES
none
RETURN VALUE
none
SIDE EFFECTS
none
