WinCE 下实现 ping 功能

来源：互联网发布：国内数据脱敏技术编辑：程序博客网时间：2024/05/29 04:56

需要包括的头文件与库文件：

#include "Winsock2.h"// PING#include "Ipexport.h"#include "Icmpapi.h"#include "winsock.h"extern HWND ghMainWnd;#pragma comment (lib, "Iphlpapi.lib") #pragma comment (lib, "Ws2.lib")

源代码如下：

int Ping(TCHAR *Address , int iTtl , int iWaitTime , TCHAR *szName , int *prtt){IPAddr                ipAddress ;IP_OPTION_INFORMATION ipInfo ;ICMP_ECHO_REPLY       icmpEcho;HANDLE                hFile;char                  strHost  [ MAX_PATH ] ;TCHAR                 szPCName [ MAX_PATH ]  = { TEXT( "" ) } ;int                   iRet = -1 ;struct in_addr iaDest;// Internet address structureLPHOSTENT pHost;// Pointer to host entry structureRETAILMSG(1,(L"TICK: %d - [TCP Client]Enter Ping......\r\n",GetTickCount() / 1000));_tcscpy( szName , TEXT("") );WideCharToMultiByte( CP_ACP, 0, Address , -1, strHost, sizeof( strHost ), NULL, FALSE );ipAddress = inet_addr(strHost);iaDest.s_addr = inet_addr(strHost);if (iaDest.s_addr == INADDR_NONE){pHost = gethostbyname(strHost);if( pHost ){char *pIP ;iaDest.S_un.S_addr = *(DWORD *)(*pHost->h_addr_list) ;pIP = inet_ntoa( iaDest ) ;if( strlen( pIP ) )MultiByteToWideChar( CP_ACP, 0, pIP , -1, szPCName, sizeof( szPCName ) );if( _tcslen( szPCName ) )_tcscpy( szName , szPCName );}}else{pHost = gethostbyaddr((const char *)&iaDest, sizeof(struct in_addr), AF_INET);if( pHost ){MultiByteToWideChar( CP_ACP, 0, pHost->h_name , -1, szPCName, sizeof( szPCName ) );if( _tcslen( szPCName ) )_tcscpy( szName , szPCName );}}if( pHost )ipAddress = *(DWORD *)(*pHost->h_addr_list) ;if (ipAddress != INADDR_NONE){iRet = 0 ;hFile = IcmpCreateFile();// Set some reasonable default valuesipInfo.Ttl   = iTtl ;ipInfo.Tos   = 0;ipInfo.Flags = 0;ipInfo.OptionsSize = 0 ;ipInfo.OptionsData = NULL ;icmpEcho.Status    = IP_REQ_TIMED_OUT/*IP_SUCCESS*/ ;IcmpSendEcho( hFile , ipAddress , NULL , 0 ,(PIP_OPTION_INFORMATION)&ipInfo,&icmpEcho , sizeof(ICMP_ECHO_REPLY) , iWaitTime ) ;IcmpCloseHandle(hFile) ;if ( icmpEcho.Status == IP_SUCCESS )iRet = 1 ;*prtt = icmpEcho.RoundTripTime ;}return iRet ;}

调用示例：

static LPTSTR strIpAddr[] = {L"202.96.209.5",// 上海 DNSL"220.181.6.18",// 百度L"202.100.4.15",// 西安 DNS};

TCHAR tcName[MAX_PATH] = {0};int iPtt = 0;

int iPingRet = Ping(strIpAddr[giPingIndex],128,3000,tcName,&iPtt);//ping tmc serverif(iPingRet == 1){RETAILMSG(1, (TEXT("TICK: %d - Ping IP: %s Success.\r\n"),GetTickCount() / 1000, strIpAddr[giPingIndex]));}else

// 失败
