Functions

	Name	Description
void	Cancel()	Cancel the request. This is a non-blocking async call and so does not ensure completion!
void	CancelImpl()	Cancel the request. This is a non-blocking async call and so does not ensure completion!
uint8 *	GetReadResults()	Return the bytes of a completed read request. Not legal to call unless the request is complete.
int64	GetSizeResults()	Return the size of a completed size request. Not legal to call unless the request is complete.
bool	PollCompletion()	Nonblocking poll of the state of completion.
void	SetAllComplete()
void	SetComplete()
void	SetDataComplete()
bool	WaitCompletion ( float TimeLimitSeconds )	Waits for the request to complete, but not longer than the given time limit
void	WaitCompletionImpl ( float TimeLimitSeconds )	Waits for the request to complete, but not longer than the given time limit
