Starts the asynchronous operation.

Copy 
STDMETHOD(  
   Start  
)(void);

S_OK if the operation starts or is already started; otherwise, E_ILLEGAL_STATE_CHANGE.

Start() is a default implementation of IAsyncInfo::Start, and does no actual work. To actually start an asynchronous operation, override the OnStart() pure virtual method.
