看样子是Windows Mobile平台,  没错，正是ConnMgrQueryDetailedStatus这个API

HRESULT WINAPI ConnMgrQueryDetailedStatus(
  CONNMGR_CONNECTION_DETAILED_STATUS *pStatusBuffer,
  DWORD *pcbBufferSize
);

typedef struct _CONNMGR_CONNECTION_DETAILED_STATUS{

  struct _CONNMGR_CONNECTION_DETAILED_STATUS* pNext;

  DWORD dwVer;

  DWORD dwParams;

  DWORD dwType;

  DWORD dwSubtype;

  DWORD dwFlags;

  DWORD dwSecure;

  GUID guidDestNet;

  GUID guidSourceNet;

  TCHAR* szDescription;

  TCHAR* szAdapterName;

  DWORD dwConnectionStatus;

  SYSTEMTIME LastConnectTime;

  DWORD dwSignalQuality;

  CONNMGR_CONNECTION_IPADDR* pIPAddr;

} CONNMGR_CONNECTION_DETAILED_STATUS;

szDescription  就是APN Name

示范代码

HRESULT hres;

DWORD dwSize = 0;

OLECHAR ochguid[256] = {0};
 

ConnMgrQueryDetailedStatus(NULL, &dwSize);

CONNMGR_CONNECTION_DETAILED_STATUS *pstatus = (CONNMGR_CONNECTION_DETAILED_STATUS*) malloc(dwSize);

 

hres = ConnMgrQueryDetailedStatus(pstatus, &dwSize);
 

while(pstatus != NULL)

{

// lastly connected & connected & has ip address

if( pstatus->dwConnectionStatus & CONNMGR_STATUS_CONNECTED && pstatus->dwParams & CONNMGRDETAILEDSTATUS_PARAM_LASTCONNECT && pstatus->dwParams & CONNMGRDETAILEDSTATUS_PARAM_IPADDR)

{

StringFromGUID2(pstatus->guidDestNet, ochguid, 256);

if( pstatus->pIPAddr != NULL )

{

      for( int i=0; i<pstatus->pIPAddr->cIPAddr; i++)

     {

         // Is this is what you need !!!

        // here is the three parameters from your question

        in_addr inaddress = *(in_addr*)&((sockaddr*)&pstatus->pIPAddr->IPAddr[i])->sa_data[2];

        printf("IP Address : %s \n", inet_ntoa(inaddress));

        wprintf(L"Destination GUID : %s \n", ochguid);

        if( pstatus->szAdapterName != NULL )

            wprintf(L"Adapter Name : %s \n", pstatus->szAdapterName);

        if( pstatus->szDescription != NULL )

            wprintf(L"Description : %s \n", pstatus->szDescription);

    }
}

}

pstatus = pstatus->pNext;

}

 

free(pstatus);

谢谢！我就是想要这个StringFromGUID2(pstatus->guidDestNet, ochguid, 256);

搞定了，十分感谢楼上的朋友
