While it is not clearly documented (at least not in the man pages I just checked) I think it is true that: -feof only returns TRUE if the "eof flag" is set; -the "eof flag" is not set by fseek -the "eof flatg" IS set by one of the read functions (getchar, getc, fgetc, gets, fgets, fread, etc) ONLY. Therefore, what feof tells you is if the most recent **READ OPERATION** has encountered EOF, not if the current **file position** is at EOF. If you addd a getc() in your loop, right following the fseek() you'll see the behavior you expect.
