As Rich suggested, I ran OCaml with kernel process tracing to see  
what the syscalls return.

28407 ocamlrun CALL  socketpair(0x1,0x1,0,0xbffff268)
28407 ocamlrun RET   socketpair 0
28407 ocamlrun CALL  getsockname(0x5,0xbffff204,0xbffff200)
28407 ocamlrun RET   getsockname 0

28407 ocamlrun GIO   fd 1 wrote 56 bytes
        "Exception: Unix.Unix_error (Unix.EAFNOSUPPORT, "", "").

So both socketpair and getsockname return 0 but OCaml still complains.

My version of getsockname.c below outputs:

     unix_getsockname: sock = 5, len = 0, retcode = 0
     Exception: Unix.Unix_error (Unix.EAFNOSUPPORT, "", "").

Any suggestions?

	Thanks, Joel

CAMLprim value unix_getsockname(value sock)
{
   int retcode;
   union sock_addr_union addr;
   socklen_param_type addr_len;

   addr_len = sizeof(addr);
   retcode = getsockname(Int_val(sock), &addr.s_gen, &addr_len);

   printf("unix_getsockname: sock = %d, len = %d, retcode = %d\n",
       Int_val(sock), addr_len, retcode);

   if (retcode == -1) uerror("getsockname", Nothing);
   return alloc_sockaddr(&addr, addr_len, -1);
}
