You are probably commenting about fseek() where the offset in Standard C is a
long. Will fseek (and other Standard C functions) work on files > 2 or 4 GB on
your system (I assume you have 32 bit long). Say, when you want to go ahead in
the file for 6 GB and you call fseek(fp, 1500000000, SEEK_CUR); three times in a
row?

I know, there are other methods, but I try to stay with Standard C.
