一个简单的测试程序健壮性的c程序

下面的程序用于不断的启动hello，并将其杀死。将hello换为别的可执行文件即可简单测试程序的健壮性。

#include <stdio.h>

#include <unistd.h>

int main(int argc, char* argv[])

{

int i;

int flag;

pid_t pid;

char buf[128] = {0};

printf("argc:%d\n", argc);

if (2 != argc)

{

printf("Usage:./a.out 3\n");

return 0;

}

int total_times = atoi(argv[1]);

for(i = 0; i < total_times; i++)

{

// 如果不指定全路径，则只检查PATH变量中存储的命令

if((pid = fork())==0) {

printf("in child process 1......\n");

//flag = execvp("./hello", NULL);

//envp变量的用

char *envp[]={"PATH=.", NULL};

flag = execve("/usr/local/test/code/hello", NULL, envp);

if(flag == -1)

printf("exec error!\n");

return 0;

}

else

{

printf("pid is:%d\n", pid);

sprintf(buf, "kill -9 %d", pid);

printf("buf is:%s\n", buf);

sleep(1);

system(buf);

}

}

printf("in parent process ......\n");

return 0;

}
