RE: Help!! --/dev/ttyS0 input overflow error --
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 began to get these on one of my systems, I disabled the com port in the bios and added a serial card... works fine now. The office building is very supceptable to close lightning strikes, and I presume emf is inducing current into the serial/mouse lines, frying it :( -- Walter L.

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) -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Re: Help!! --/dev/ttyS0 input overflow error --
I can't help you with the device problem. However, if you do a: man fflush You will get a manual page of the fflush C function for the particular UNIX or UNIX-like system you are using, presumably and hopefully Debian Linux since you posted to this Debian mailing list. In general, all available C routines have man pages. Here is some of the output from the above man page: FFLUSH(3) Linux Programmer's Manual FFLUSH(3) NAME fflush - flush a stream SYNOPSIS #include stdio.h int fflush(FILE *stream); DESCRIPTION see the man page :-) Good luck. -Ossama __ Ossama Othman [EMAIL PROTECTED] --- PGP Keys --- Public: http://astrosun.tn.cornell.edu/staff/othman/OO_PUBLIC.asc REVOKED: http://astrosun.tn.cornell.edu/staff/othman/OO_REVOKED.asc -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

RE: Help!! --/dev/ttyS0 input overflow error --
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. jim -- From: C.J.LAWSON[SMTP:[EMAIL PROTECTED] Sent: Thursday, February 26, 1998 9:02 AM To: debian-user@lists.debian.org Cc: The recipient's address is unknown.
