谁能给写个vc++下可调用的ping函数

#include <stdio.h>

#include <stdlib.h>

int ping(char * ip)

{

int ok = 1FILE * f = 0

char cmd[80]=""sprintf(cmd, "汪孝毕ping %s >ping.txt", ip)

system(cmd)

f = fopen("ping.txt", "r")

if(!f) return 0

while(!feof(f)) {

fgets(cmd, 80, f)

if(strstr(cmd, "timed out")) ok = 0

}/*end while*/

system("del ping.txt")

return ok

}

int main(void)

{

int ok = ping("192.168.1.1")

if(ok) printf("目标连通！")else printf("网络不通！")

return 0

}

看明白了没有？system命令把ping结果困芹存到一个ping.txt的临时文件里面，然后检验文件内容是否有“超时”的字样，如果有则慎培返回“不通”。

1、“文件”->“新建...”->“项目...”，在“已安装的模板”下选择“Visual C++”，并选择“Win32”下的“Win32控制台应用程序”，陆则输入解决方案名后“确定”，之后“下一步”，勾选“空项目”后“完成”。

2、在“解决方案资源管理早皮棚握虚器”中展开项目后，右击“源文件”后选择“添加...”->“新建项...”，在“已安装的模板”下的“Visual C++”中选择“C++源文件(.cpp)”添加即可。
