C 链接列表，路径到大小的应用无效不完整类型

我在编译代码时遇到了一个无效的应用程序大小路径错误，但我自己找不到问题，有人能帮忙吗

/*********************************************************
* Node to represent a packet which includes a link reference*
* a link list of nodes with a pointer to a packet Struct    *

**********************************************************/
struct node {
unsigned int Source;
unsigned int Destination;
unsigned int Type;
int Port;
char *Data;
struct Packet *next;
 // Link to next packet

//unassigned int source
//unassigned int destination
//int type
//unassigned int port
//char *data
//struct node  *next link to next node
};

typedef struct Packet node; // Removes the need to constantly refer to struct


/*********************************************************
* Stubs to fully declared functions below                *
**********************************************************/
void Outpacket(node **head);
void push(node **head, node **aPacket);
node* pop(node **head);

int main() {

/*********************************************************
* pointers for the link list and the temporary packeyt to    *
* insert into the list                                   *
**********************************************************/
node *pPacket, *phead = NULL;

/*********************************************************
* Create a packet and also check the HEAP had room for it   *
**********************************************************/
pPacket = (node *)malloc(sizeof(node));
if (pPacket == NULL)
{
    printf("Error: Out of Memory\n");
    exit(1);
}

这只是完整代码的一部分，但断点发生在以下行：

pPacket = (node *)malloc(sizeof(node));

感谢您的帮助

这可能是因为您使用的是结构数据包，没有定义它

在

struct节点的定义中，您使用的是
struct-Packet*
。但是没有所谓的
struct-Packed
。要么更改结构的名称，要么更改元素

请尝试以下操作：

struct Packet {
unsigned int Source;
unsigned int Destination;
unsigned int Type;
int Port;
char *Data;
struct Packet *next;
 // Link to next packet

//unassigned int source
//unassigned int destination
//int type
//unassigned int port
//char *data
//struct node  *next link to next node
};

typedef struct Packet node; // Removes the need to constantly refer to struct

这里，
struct Packet
和
node
是相同的结构，没有异常情况。
为什么不使用construct:

typedef struct Packet { .... } node;

您命名了struct节点，但从type指向其中的下一个元素

struct-Packet*
