MM_AbortRequest
To abort an outstanding IO request submitted by calling MM_ObjectIO.
LONG MM_AbortRequest (HNDL messageHandle );
The following table lists return values and descriptions.
The callback routine passed to MM_ObjectIO will be called when the message is aborted. The IO return value will be either MM_ABORTED_CLEAN, indicating that the message was aborted before being submitted to a device, or MM_ABORTED_UNCLEAN, indicating that the message has been sent to a device. If the message is in the process of completing when the abort request is submitted, then the return value will be defined by the driver as in any other IO request.
