File I/O

msm · 11-21-2009, 01:56 AM

Hi,

I am writing a C program that reads from a log file that another running application is writing to.
Are there any sort of contention issues I need to worry about? Do I have to worry about stalling my program if the other application has not written the next event yet?

The other application simply writes 1 line at a time, and prints "#eof\n" when it is completely finished and it shuts down.
I want to read one line at a time in my application and end when the other application shuts down.

Thanks for the advice!

It's really up to your OS if you can access the same file by multiple programs at the same time.
