See the fine manual:

It doesn't seem to me that this answers the original question.  I
think a better answer is that there is no provision currently to turn
SBCL functionality into a library in the usual sense of being able to
link to it from C.  The manual section that Nikodemus refers to is
about being able to link in C libraries to a lisp environment, which
may be enough for certain needs.

which lisp versions are you refering to?

None of lisp implementations that I know provide such shared libraries 
(dll export or whatever), rather these are standalone executables which 
happen to use some image file.
(my knowledge in lisp is limited, so I could be wrong)

This means you usually do other way round - call your C application from 
LISP and this ways establish a connection.

Some lisp could provide static libraries for linkage, however. (like 
"linking set" in CLISP)

LW does it.  Allegro does too.   Among the "free" implementations ECL  
(http://ecls.sf.net) was built exaclty with that goal in mind.  I  
think I remember someone dabbling with SBCL (or was it CMUCL?!?) to  
achieve the same effect.

Clisp can also be used this way, I think.

very much thanks for opening my eyes :)

IMO any package providing static libraries is "prepared" for dynamic 
loading also.
DLL-wrapper for windows is easy.

With best regards,
