Closes the asynchronous operation.
STDMETHOD(
Close
)(void) override;
S_OK if the operation closes or is already closed; otherwise, E_ILLEGAL_STATE_CHANGE.
Remarks
Close() is a default implementation of IAsyncInfo::Close, and does no actual work. To actually close an asynchronous operation, override the OnClose() pure virtual method.
