From: cadtroy!schoff@cadmus Firstly: In the File Manager Programmer's Guide under the File I/O Queue (6-59) we have an interesting FIFO. What exactly is the "rest of parameter block". What does it look like etc.... Secondly: If control has passed to "toExtFS" can I assume that the first queue entry refers to the external file system (ExtFS)? Thirdly: If I am smart given the slow speed of the appletalk and the asynchronous nature of the I/O should I scan through queue and look for other I/O request that refer to the ExtFS and maybe even violate the FIFO approach but minimally check the "second" I/O request? marty schoff@cadmus.ARPA schoff@cadmus.CSNET seismo!ucadmus!cadtroy!schoff sbcs!albany!cadtroy!schoff
