标题: 一个C语言的问题，请教高手
#define MC_RTK_OFSM( OperationType, Transition, NextState ) \
(const t_OperationDescriptor *((*)(t_RtkObject *)))Transition, NextState, OperationType, MC_PCC_FILL_INISTRUCT2
static void hsc1_49BirdDisplayGraphic(t_FsmObject * pp_Object)
typedef struct st_RtkObject {
union {
   t_TimerID v_TimerID;             /* OUT: Timer ID received */
   PACKED struct st_MsgHeader *p_MessageAddress;       /* OUT: Message received */
   u16       v_UserEvent;             /* OUT: User events occured */
}u_ReceivedObj;
u32          v_UserData;             /* OUT: Pointer to an Area used to store */
u16          v_UserEventMask;       /* IN:  User events to wait */
u8             v_TypeOfObj;             /* OUT: Type of object in the union */
MC_PCC_FILL_STRUCT1
}t_RtkObject;
typedef struct st_RtkObject t_FsmObject; /* for existing programs */
t_OperationDescriptor *((*)(t_RtkObject *)))Transition, 这个中的Transition是一个函数，原型是
void Transition(t_FsmObject *),但前边的转换我就看不懂了，返回为void怎么能够转换为t_OperationDescriptor *呢

应该是void *吧？猜的。
