NAME
    AbortIO - attempt to abort an in-progress I/O request

SYNOPSIS
    AbortIO(iORequest)
            A1

    VOID AbortIO(struct iorequest *);

FUNCTION
    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.

NOTE
    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.

EXAMPLE
        AbortIO(timer_request);
        WaitIO(timer_request);
        /* message is free to be reused */

INPUTS
    iORequest - pointer to an I/O request block (must have been used
            at least once.  May be active or finished).
