Look up feof().

Where did you get such a big disk drive? Who put the endless file
on it? What software did they use. Where did they get the data to
write to the file?

Stop calling fread() ? close the file? :-)


Seriously however, read up on feof().

Reading a file is not addictive, so it's just a matter of not
reading any more from it.

Btw, what do you mean with "with no EOF"? I can think of a few
examples, like /dev/zero and /dev/random on unix systems, is that
what you mean?

He's probably writing a quality-control test program
to make sure /dev/zero contains only zeroes ;-)

The system should report to stdio the end of a disk file and stdio
reports that with EOF or NULL returns or feof. For a file like a
serial port or keyboard, you may have to define your own protocol
within the file to work the end.

Dear Joe,

I do read in this forum.But i believe that there is a couple of ways to go
around reading a file without the use of eof, either by seeking to end of
file through lseek, or getting size of the file and decrementing a counter
(which would be initialized to file size) until it hits zero.
It depends on the task.

But thanks for the tip.
