需要包括的头文件与库文件:

 1 #include "Winsock2.h"  
 2 // PING  
 3 #include "Ipexport.h"  
 4 #include "Icmpapi.h"  
 5 #include "winsock.h"  
 6   
 7 extern HWND ghMainWnd;  
 8   
 9 #pragma comment (lib, "Iphlpapi.lib")   
10 #pragma comment (lib, "Ws2.lib")   

源代码如下:

 1 int Ping(TCHAR *Address , int iTtl , int iWaitTime , TCHAR *szName , int *prtt)  
 2 {  
 3     IPAddr                ipAddress ;  
 4     IP_OPTION_INFORMATION ipInfo ;  
 5     ICMP_ECHO_REPLY       icmpEcho;   
 6     HANDLE                hFile;      
 7     char                  strHost  [ MAX_PATH ] ;  
 8     TCHAR                 szPCName [ MAX_PATH ]  = { TEXT( "" ) } ;  
 9     int                   iRet = -1 ;  
10     struct in_addr iaDest;      // Internet address structure  
11     LPHOSTENT pHost;            // Pointer to host entry structure  
12   
13     RETAILMSG(1,(L"TICK: %d - [TCP Client]Enter Ping......\r\n",GetTickCount() / 1000));  
14   
15     _tcscpy( szName , TEXT("") );  
16     WideCharToMultiByte( CP_ACP, 0, Address , -1, strHost, sizeof( strHost ), NULL, FALSE );  
17     ipAddress = inet_addr(strHost);  
18     iaDest.s_addr = inet_addr(strHost);  
19     if (iaDest.s_addr == INADDR_NONE)  
20     {  
21         pHost = gethostbyname(strHost);  
22         if( pHost )  
23         {  
24             char *pIP ;  
25             iaDest.S_un.S_addr = *(DWORD *)(*pHost->h_addr_list) ;  
26             pIP = inet_ntoa( iaDest ) ;  
27             if( strlen( pIP ) )  
28                 MultiByteToWideChar( CP_ACP, 0, pIP , -1, szPCName, sizeof( szPCName ) );  
29             if( _tcslen( szPCName ) )  
30                 _tcscpy( szName , szPCName );  
31         }  
32     }  
33     else  
34     {  
35         pHost = gethostbyaddr((const char *)&iaDest,   
36             sizeof(struct in_addr), AF_INET);  
37         if( pHost )  
38         {  
39             MultiByteToWideChar( CP_ACP, 0, pHost->h_name , -1, szPCName, sizeof( szPCName ) );  
40             if( _tcslen( szPCName ) )  
41                 _tcscpy( szName , szPCName );  
42         }  
43     }  
44     if( pHost )  
45         ipAddress = *(DWORD *)(*pHost->h_addr_list) ;  
46     if (ipAddress != INADDR_NONE)  
47     {     
48         iRet = 0 ;  
49         hFile = IcmpCreateFile();  
50   
51         // Set some reasonable default values  
52         ipInfo.Ttl   = iTtl ;  
53         ipInfo.Tos   = 0;  
54         ipInfo.Flags = 0;  
55         ipInfo.OptionsSize = 0 ;  
56         ipInfo.OptionsData = NULL ;  
57         icmpEcho.Status    = IP_REQ_TIMED_OUT/*IP_SUCCESS*/ ;  
58         IcmpSendEcho( hFile , ipAddress , NULL , 0 ,  
59             (PIP_OPTION_INFORMATION)&ipInfo,  
60             &icmpEcho , sizeof(ICMP_ECHO_REPLY) , iWaitTime ) ;   
61         IcmpCloseHandle(hFile) ;  
62         if ( icmpEcho.Status == IP_SUCCESS )  
63             iRet = 1 ;  
64   
65         *prtt = icmpEcho.RoundTripTime ;  
66     }  
67     return iRet ;  
68 }  

调用示例:

 1 static LPTSTR strIpAddr[] =   
 2 {  
 3     L"202.96.209.5",    // 上海 DNS  
 4     L"220.181.6.18",    // 百度  
 5     L"202.100.4.15",    // 西安 DNS  
 6 };  
 7 
 8 TCHAR tcName[MAX_PATH] = {0};  
 9 int iPtt = 0;  
10 int iPingRet = Ping(strIpAddr[giPingIndex],128,3000,tcName,&iPtt);  //ping tmc server  
11   
12 if(iPingRet == 1)  
13 {  
14     RETAILMSG(1, (TEXT("TICK: %d - Ping IP: %s Success.\r\n"),GetTickCount() / 1000, strIpAddr[giPingIndex]));  
15 }  
16 else  
17 {  
18 }
