簡單的windows作業管理（自己也沒弄透徹）

先把代碼貼出來，以後有時間再研究！簡單的說，作業就相當於沙箱，可以使程式在一定範圍內活動。

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

SECURITY_ATTRIBUTES sa;
STARTUPINFO si={sizeof(si)};
PROCESS_INFORMATION pi;

void main()
{

HANDLE hjob=CreateJobObject(&sa,"test");

JOBOBJECT_BASIC_LIMIT_INFORMATION jb;
jb.PriorityClass=IDLE_PRIORITY_CLASS;
jb.PerProcessUserTimeLimit.QuadPart=1000;

JOBOBJECT_BASIC_UI_RESTRICTIONS jbur;

jbur.UIRestrictionsClass = JOB_OBJECT_UILIMIT_NONE|

JOB_OBJECT_UILIMIT_EXITWINDOWS | JOB_OBJECT_UILIMIT_HANDLES;

SetInformationJobObject(hjob,
JobObjectBasicLimitInformation,
&jb,
sizeof(JOBOBJECT_BASIC_LIMIT_INFORMATION)
);

SetInformationJobObject(hjob,JobObjectBasicUIRestrictions,&jbur,sizeof(jbur));

CreateProcess(NULL,"ping www.baidu.com -t",NULL,NULL,TRUE,CREATE_SUSPENDED|CREATE_NEW_CONSOLE,NULL,NULL,&si,&pi);

 

AssignProcessToJobObject(hjob,pi.hProcess);

ResumeThread(pi.hThread);
CloseHandle(pi.hThread);

FILETIME CreationTime, ExitTime, KernelTime, UserTime;

GetProcessTimes(pi.hProcess, &CreationTime, &ExitTime, &KernelTime, &UserTime);

// GetProcessTimes(GetCurrentProcess, &CreationTime, &ExitTime, &KernelTime, &UserTime);

cout << TEXT("Kernel = ") << KernelTime.dwLowDateTime << " and User = "

<< UserTime.dwLowDateTime << endl;

 

CloseHandle(pi.hProcess);
CloseHandle(hjob);
system("pause");
}
