AbortIO - attempt to abort an in-progress I/O request
AbortIO(iORequest)
A1
VOID AbortIO(struct IORequest *);
Ask a device to abort a previously started IORequest. This is done
by calling the device's ABORTIO vector, with your given IORequest.
AbortIO is a command the device that may or may not grant. If
successful, the device will stop processing the IORequest, and
reply to it earlier than it would otherwise have done.
AbortIO() does NOT Remove() the IORequest from your ReplyPort, OR
wait for it to complete. After an AbortIO() you must wait normally
for the reply message before actually reusing the request.
If a request has already completed when AbortIO() is called, no
action is taken.
AbortIO(timer_request);
WaitIO(timer_request);
/* Message is free to be reused */
iORequest - pointer to an I/O request block (must have been used
at least once. May be active or finished).
