Any way to link C funcs to LISP?

[David Hand]

I would like to write a font-end to a C program that uses LISP. This
would allow users to dynamically interact with the program somewhat like
AutoLISP. I'm doing this under Windows NT. Do any commercial LISP
compilers allow you to bind C funcs from a DLL to a LISP function? So
for example, the C program might have a function:

draw_line(int x1, int y1, int x2, int y2)

and I want to then be able to exectute:

(draw_line 3 5 10 12)

from within the LISP front-end.

Any help would be appreciated.

Thanks
