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