In reading through the AmigaDOS Manual, (V1.1, Bantam) in the section on Lock in the AmigaDOS Technical Manual section, it describes usefulness of locks for checking if a file exists, Lock() having lower overhead than Open(), and says that locks are used extensively by AmigaDOS. Fine. It also says that locks can also be used for asynchronous I/O, but does not describe HOW. Can you Lock() a file and use packets to the filesystem handler to do asynchronous I/O to AmigaDOS files without even having to call Open()? If so, how do you do this? Deven -- Deven T.
