如何用C语言调用ping命令

C语言调用ping命令，参考代码：

#include <windows.h>

#include <stdio.h>

#include <string.h>

char YN(int k) {

    FILE *f

    char fn[40]

    char ln[80]

    char yn

   薯弊岩 int n

    数御yn='N'

    sprintf(fn,"d:\\ping%d.txt",k)

    f=fopen(fn,"r")

    if (NULL!=f) {

        n=0

        while (1) {

            if (NULL==fgets(ln,80,f)) break//

            if (strstr(ln,"ms ")) {

                yn='Y'

                break//

            }

            n++

            if (n>=4) break//

        }

        fclose(f)

    }

    return yn

}

void main(int argc,char **argv) {

    char cmdstr[256]

    int i

    int IP[3]

    char c

    if (argc<2) {

    USAGE:

        printf("Usage example:\n    %s 192.168.60.\nto test 192.168.60.1-254\n",argv[0])

        return

    }

    if (4==sscanf(argv[1],"%d.%d.%d%c",&IP[0],&IP[1],&IP[2],&c)) {

        if (0<=IP[0] && IP[0]<=255

     卜此    && 0<=IP[1] && IP[1]<=255

         && 0<=IP[2] && IP[2]<=255

         && '.'==c) {

            for (i=1i<255i++) {

                sprintf(cmdstr,"cmd /c ping %s%d -n 1 -w 1000 >d:\\ping%d.txt",argv[1],i,i)

                WinExec(cmdstr,SW_HIDE)

            }

            Sleep(3000)

            for (i=1i<255i++) {

                printf("%c %s%d\n",YN(i),argv[1],i)

            }

            Sleep(3000)

            WinExec("cmd /c del /q d:\\ping*.txt",SW_HIDE)

        } else goto USAGE

    } else goto USAGE

}

/含袜者/关键代码如下：

#include "icmpapi.h"

#include "iphlpapi.h"

#pragma comment(lib,"谈薯iphlpapi.lib")

bool CPINGDlg::startping(char* IP) //成功好孝返回true, 失败返回false

{

HANDLE hIcmpFile = NULL

unsigned long ipaddr = INADDR_NONE

DWORD dwRetVal = 0

char SendData[] = "Data Buffer\0"

LPVOID ReplyBuffer = NULL

DWORD ReplySize = 0

// PICMP_ECHO_REPLY reply

ipaddr = inet_addr(IP)

ReplySize = sizeof(ICMP_ECHO_REPLY)+sizeof(SendData)

ReplyBuffer = (void*)malloc(ReplySize)

hIcmpFile = IcmpCreateFile()

if (hIcmpFile == INVALID_HANDLE_VALUE)

{

AfxMessageBox(_T("Ping 内部代码错误"))

return false

}

dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData), NULL, ReplyBuffer, ReplySize, 1000)

// CloseHandle(hIcmpFile)

// free(ReplyBuffer)

if (dwRetVal != 0)

{

return true

}

else

{

return false

}

}
