I think you need to define the interface to have a getpid method with
the proper signature. Here is a small example, somewhat similar to your
code, that I tried a while back and that works:
(define-simple-class clib (com.sun.jna.Library)
interface: #t
((puts (s ::String)) ::void #!abstract))
((as clib
(com.sun.jna.Native:loadLibrary "c" clib)):puts "Hello, World!")
