使用C语言的链表

我试图创建一个链表，在每个节点上都有一个指向不同类型的单独链表的指针。这就是问题所在，第一个列表（X）创建得很好，但我创建的是一个链接列表（Y），X的所有节点都指向该列表，而不是X的每个节点都指向一个唯一的Y。我希望这是有意义的。以下是我的代码：

struct PathNodeStruct {
  char CurrentPathMovement;
  struct PathNodeStruct * prev;
  struct PathNodeStruct * next;
};
typedef struct PathNodeStruct PathNode;
typedef struct PathNodeStruct * PathNodePtr;
struct PathNodeStruct * head = NULL;

struct RoomNodeStruct {
  int roomNumber;
  struct PathNode * pathStart;
  struct RoomNodeStruct * next;
};
typedef struct RoomNodeStruct RoomNode;
typedef struct RoomNodeStruct * RoomNodePtr;
struct RoomNodeStruct * roomHead = NULL;

void insertPathNode(char move){
if(head == NULL){   //case if first node in list
    head = (PathNodePtr)malloc(sizeof(PathNode));
    if(head != NULL){
        head->CurrentPathMovement = move;   //sets data in node
        head->prev = NULL; //sets links up
        head->next = NULL;
    } else{
        printf("ERROR");
        }
} else{
    PathNodePtr cursorPtr = head;
    while(cursorPtr->next != NULL){   //cursors to end of list
        cursorPtr = cursorPtr->next;
    }
    PathNodePtr newPathNodePtr = (PathNodePtr)malloc(sizeof(PathNode)); //allocates for node to be added
    if(newPathNodePtr != NULL){
        cursorPtr->next = newPathNodePtr;
        newPathNodePtr->prev = cursorPtr;   //sets links up
        newPathNodePtr->next = NULL;
        newPathNodePtr->CurrentPathMovement = move; //sets data in node
    } else{
        printf("ERROR");
    }
}


void insertRoomNode(int value){
if(roomHead == NULL){   //case if first node in list
    roomHead = (RoomNodePtr)malloc(sizeof(RoomNode));
    if(roomHead != NULL){
        roomHead->roomNumber = value;   //sets data in node
        roomHead->next = NULL;
        roomHead->pathStart = head;
    } else{
        printf("ERROR ALLOCATING IN INSERT ROOM NODE.");
        }
} else{
    RoomNodePtr cursorPtr = roomHead;
    while(cursorPtr->next != NULL){   //cursors to end of list
        cursorPtr = cursorPtr->next;
    }
    RoomNodePtr newRoomNodePtr = (RoomNodePtr)malloc(sizeof(RoomNode)); //allocates for node to be added
    if(newRoomNodePtr != NULL){
        cursorPtr->next = newRoomNodePtr;
        newRoomNodePtr->next = NULL;
        newRoomNodePtr->roomNumber = value; //sets data in node
        newRoomNodePtr->pathStart = head;
    } else{
        printf("ERROR ALLOCATING IN INSERT ROOM NODE.");
    }
}

这是用于MUD服务器的吗？

roomHead->pathStart=head我认为这是没有必要的。因为
head
是全局变量。不需要作为单独的成员保留。对于MUD服务器不需要
