I don't know about your first problem...

fflush() will flush your stream to the system buffer cache.  sync() will cause
the buffer cache to be posted to disk.  Unless linux crashes, the sync call
should not be needed.

Hi everyone,
	I wote some code to manage a data aquisition device in the labs.
It runs for a while (say 24 hrs, gathering data every 6 secs [x 50 data
points]) then it crashes, crashes bad (segmentation fault) /dev/ttyS0
input overflow ... does anyone know what is causing this??
	I would also like to find out what the equivalent of fflush (); is
for the unix filesystem

	Thanks and I really look forward to hearing from you 
	
	Regards
		
		Jonatha (who is in a fix in the lab)
