If fseek() always clears EOF, is there a way for me to fread() from an
offset of a file and still be able to detect EOF?

Please explain how the several previous answers to your several
previous similar questions are inadequate.

I still don't know how can I detect EOF

By readin the previous answers. All the IO functions return status
messages which will tell you when you found the end of a file.

I must be able to seek forwards and
backwards in the file, but I still don't know up to now how can I do
this without fseek(), that's why I posted this question.

You can do it with fseek, thats what its for. However its up to you to
ensure your seeks remain inside the file by some other means. A
trivial way to do this is to determine the file size never seek
further than that from the start of the file.
