关于NetworkGuid的数据类型

[黑夜愁客]

在NET_IF_NETWORK_GUID中有一个变量叫做 NET_IF_NETWORK_GUID

do {

        pAddresses = (IP_ADAPTER_ADDRESSES *) MALLOC(outBufLen);
        if (pAddresses == NULL) {
            printf
                ("Memory allocation failed for IP_ADAPTER_ADDRESSES struct\n");
            exit(1);
        }

        dwRetVal =
            GetAdaptersAddresses(family, flags, NULL, pAddresses, &outBufLen);

        if (dwRetVal == ERROR_BUFFER_OVERFLOW) {
            FREE(pAddresses);
            pAddresses = NULL;
        } else {
            break;
        }

        Iterations++;

    } while ((dwRetVal == ERROR_BUFFER_OVERFLOW) && (Iterations < MAX_TRIES));

    if (dwRetVal == NO_ERROR) {
        // If successful, output some information from the data we received
        pCurrAddresses = pAddresses;
        while (pCurrAddresses) {
          //这里我想出书guid值
         printf("GUID values is %lu",pCurrAddresses->NetworkGuid);//但是我不知道NetworkGuid数据类型所以出错

所以让你帮忙看看这是什么类型的数据，怎么才能正确输出呢？个人觉得正确输出结果应该类似：
GUID: b568ee76-6d17-4a3a-a2f5-269c52fd6de7

char szBuf[64];

sprintf_s(szBuf, 64, "{%08x-%04x-%04x-%02X%02X-%02X%02X%02X%02X%02X%02X}",
    pCurrAddresses->NetworkGuid->Data1, pCurrAddresses->NetworkGuid->Data2, pCurrAddresses->NetworkGuid->Data3,
    pCurrAddresses->NetworkGuid->Data4[0], pCurrAddresses->NetworkGuid->Data4[1],
    pCurrAddresses->NetworkGuid->Data4[2], pCurrAddresses->NetworkGuid->Data4[3],
    pCurrAddresses->NetworkGuid->Data4[4], pCurrAddresses->NetworkGuid->Data4[5],
    pCurrAddresses->NetworkGuid->Data4[6], pCurrAddresses->NetworkGuid->Data4[7]);

printf("%s", szBuf);

谢谢各位

我现在读出来的是一堆数字：GUID:3801794241

打开Iphlpapi.h头文件看看不就知道了吗？
估计是DWORD

在ifdef.h里定义的，就是GUID

typedef GUID NET_IF_NETWORK_GUID, *PNET_IF_NETWORK_GUID;

GUID

而GUID的定义在Guiddef.h：

#ifndef GUID_DEFINED
#define GUID_DEFINED
#if defined(__midl)
typedef struct {
    unsigned long  Data1;
    unsigned short Data2;
    unsigned short Data3;
    byte           Data4[ 8 ];
} GUID;
#else
typedef struct _GUID {
    unsigned long  Data1;
    unsigned short Data2;
    unsigned short Data3;
    unsigned char  Data4[ 8 ];
} GUID;
#endif
#endif
