Thread: How to detect an empty file?

My program reads a .txt file.

I want to check when the program detects a new line in a file. If the file is empty i, it assigns the word "Stable" to a string, if it detects a new line, the programs assign the word "Fail" to the string.

I know how to read a line in a file, but just because the program is almost stable all the time, I don't want to write that word in to the file all the time. So when the other program writes to the file is because there is a problem.

am I clear?

Thanks a lot
Daniel

ummm... which OS?

I think that you can check the size of a file with the Win32 API...

I am Using Red Hat Linux 7.2

Are you trying to mimic tail -f ?

If so, read the file until you hit EOF, then clear the file stream error settings, sleep a while and read again to see if there's new data in it.
