File streams support the file-position function, which seeks to a
given position (which is a binary position if your stream is a binary
stream)

You don't want the sb-unix package unless you really know what you're
doing, because that's an implementation-private package.  If you want
access to POSIX calls, you can use sb-posix, which is programmable (at
least in theory) by reading the Unix man pages and imagining how it
would be expressed in lisp...
