In comp.os.linux.misc General Schvantzkoph <schvantzkoph@xxxxxxxxx>:
I'm writing a system exerciser that checks memory and disk I/O. Is there a
C call that flushes the file cache so that I can be assured that my freads
are coming from the disk and not the RAM. I'm using a sync() but I don't
think that does the whole job, it guarantees that the disk writes happen
but I don't think it clears out the file cache.
There are several apps to do it iirc "bonnie" and alike a quick
search on freshmeat.net should reveal some.
Good luck
