Could anyone over there tell me how to include C subroutines which
would be written in a file  into a Lisp program and how to call them
from Common Lisp?  I need to do system call to excute some shell
commands, thus I have to write C  code to deal with it.(Is that
right?) And my routines would be called by Lisp program. Do I need
some interfaces to make the C routines be recognized by Lisp? 

Any information and suggestion would be very helpful. Thanks in
advance.
