Thanks for your help. But there are still some problems. And this time I
only use a small piece of code.

#ifndef NULL
#define NULL        0

typedef struct T_VMK_ChainNode_Struct T_VMK_ChainNode;
struct T_VMK_ChainNode_Struct
  T_VMK_ChainNode *next;
  T_VMK_ChainNode *previous;

typedef struct
  T_VMK_ChainNode *head;
  T_VMK_ChainNode *null;
  T_VMK_ChainNode *tail;
} T_VMK_ChainControl;

    requires \valid(chain);
    ensures \result != NULL;
VMK_INLINE T_VMK_ChainNode *_ChainHead( T_VMK_ChainControl *chain )
   return (T_VMK_ChainNode *) chain;
tang at tang-desktop:~/Desktop/test_verify_SVMK$ frama-c -jessie  ./list.c
[kernel] preprocessing with "gcc -C -E -I.  -dD ./list.c"
./list.c:28:[kernel] user error: syntax error
[kernel] user error: skipping file "./list.c" that has errors.
[kernel] Plugin kernel aborted because of invalid user input(s).
