The debug engine (DE) sends this interface to the session debug manager (SDM) when the program is about to execute its first instruction of user code.
The DE creates and sends this event object when the program being debugged has been loaded and is ready to execute the first instruction of user code. The event is sent by using the IDebugEventCallback2 callback function that is supplied by the SDM when it attached to the program being debugged.
IDebugLoadCompleteEvent2 is sent when the program is about to execute the very first instruction. For example, IDebugEntryPoint2 is sent when the program is about to execute the user's main function.
When the DE sends IDebugEntryPointEvent2, the current code position should be at the first instruction of user code, like main.
