Since fputs doesn't add a line break automatically, you have to add it explicitly.

    fputs(tmpbuf, logfile);
    fputs("\n", logfile);

unless I'm missing something you'd need to add a 2nd fputs for the newline or go back to fprintf like before the latest comment.

I have gone back to fprintf for consistency as you mentioned above. Newline is included. Thanks!

fflush(logfile);
