/*  SYNOPSIS */
	AROS_LHA(struct IORequest *, iORequest, A1),

/*  LOCATION */
	struct ExecBase *, SysBase, 80, Exec)

/*  FUNCTION
	Calls the AbortIO vector of the appropriate device to stop an
	asynchronously started io request before completion. This may
	or may not be done. You still have to do a WaitIO() on the
	iorequest structure.

    INPUTS
	iORequest - Pointer to iorequest structure.

    RESULT
	Errorcode if the abort request failed, 0 if the abort request went
	well. io_Error will then be set to IOERR_ABORTED.
