Has anyone had any experience writing programs that do asynchronous
disk IO on MS-DOS?  What's the best way for doing it?

Thanks.

-------------------
Note:
Asynchronous Disk IO is a method of accessing disks where the program that
wants to do the accessing starts the read or write tasks and goes on with
whatever else it is doing.  The system informs the program that it is done
through either a polling mechanism (where the program periodically asks the
system: "are you done?") or an interrupt mechanism.  The idea is that useful
computations can be performed when the disk is being accessed.
