is_completed()

virtual bool xtd::iasync_result::is_completed ( ) const

pure virtualnoexcept

Gets a value that indicates whether the asynchronous operation has completed.

Returns

true if the operation is complete; otherwise, false.

Remarks

When this property is true, you can assume it is safe to discard any resources you allocate for use by the asynchronous operation.

Notes to Implementers

Implementers will typically return the value of a private field or internal test as the value of this property.

Notes to Callers

Clients that poll for operation status (as opposed to waiting on a synchronization object) use this property to determine the status of the operation.
