Terminating Data Transfer Operations

The function URLAbort terminates a data transfer operation that was started by any function transferring data to or from a URL reference, including URLDownload, URLUpload, and URLOpen. When your application calls URLAbort, URL Access Manager changes the state returned by the function URLGetCurrentState to kURLAbortingState and passes the constant kURLAbortInitiatedEvent to your notification callback function. When data transfer is terminated, URL Access Manager changes the state returned by URLGetCurrentState to kURLCompletedState and passes the constant kURLCompletedEvent in the event parameter of your notification callback function.
