Ok, another question about AmigaDOS:

Is it possible to force the file-system(s) to write out their buffered
data?  In my program, I write a (sometimes) large file (>400K) and then
inhibit the filesystem in order to read bitmaps, etc.  Right now I just
Delay(300) or so to let the FS finish flushing bitmaps and such.  However,
this seems like a bad way of doing it, especially since it is possible that
the FS won't get a chance to run due to other procs running at a higher
priority.  There are packets for "ACTION_DISKCHANGE" but I think that
these are obsolete.  The Inhibit packet seems to cause troubles if 
DoIO()'ed while the bitmaps are bad.  I think I remember experimenting
and finding that C:DiskChange will screw up a disk if issued right
after writing to a disk, which leads me to believe there is no
good way to do it right.
Right now, the Delay() seems to be OK, but I'm interested in knowing 
if there is a better way. Thanks!!!  -- Darren
