c语言进程管理程序

代码如下

#include "stdafx.h"
#include<windows.h>
#include<tlhelp32.h>
#include<string>
#include <iostream>
using namespace std;

    return 0;
  }
  else{
    printf("kill process faild\n");
    return 0;
  }

  CloseHandle(hProcess);

}

int GetProcess(){
  char buff[1024] = { 0 };

    return 0;
  }

  BOOL  bProcess = Process32First(hProcessSnap,&pe32);

    printf(buff);
    memset(buff, 0x00, 1024);
    bProcess = Process32Next(hProcessSnap, &pe32);
  }
  CloseHandle(hProcessSnap);
  return 0;
}
