Ok, here's a question that I haven't yet been able to get answered (although I haven't talked with DTS). I have an open file that I would like to keep open. I would also like to ensure that all that I have already written is actually put on the disk. Question: Is FlushVol() guanteed to work for all of the outstanding write requests, or only for those where the file has been closed. IM doesn't explicitly say what FlushVol() depends on. -- Mike Rutenberg Software Engineer & Short Order Cook (503) 771-5516

I've used FlushVol on open files to keep the information current. I don't
know if it actually works, though.
One call that is guaranteed to work is PBFlushFile(). The parameter block
you set up has the access path number (the third argument to FSOpen()) stored
in the ioRefNum field; be sure to clear IOCompletion.
It's described on Inside Mac Volumne II, page 114.
