Windows C++ 启动子进程并绑定子进程，主进程结束关闭后自动结束关闭子进程

// 启动子进程STARTUPINFOStartupInfo;
PROCESS_INFORMATIONProcessInformation;
ZeroMemory(&StartupInfo, sizeof(StartupInfo));
ZeroMemory(&ProcessInformation, sizeof(ProcessInformation));
StartupInfo.cb=sizeof(StartupInfo);
StartupInfo.wShowWindow=SW_SHOW;
CreateProcess(L"child.exe", nullptr, nullptr, nullptr, 0, 0, nullptr, nullptr, &StartupInfo, &ProcessInformation);
// 把子进程加入到作业中HANDLEHandleJob=CreateJobObject(nullptr, nullptr);
if(AssignProcessToJobObject(HandleJob, ProcessInformation.hProcess))
    {
JOBOBJECT_EXTENDED_LIMIT_INFORMATIONLimitInfo;
ZeroMemory(&LimitInfo, sizeof(LimitInfo));
LimitInfo.BasicLimitInformation.LimitFlags=JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE; 
SetInformationJobObject(HandleJob, JobObjectExtendedLimitInformation, &LimitInfo, sizeof(LimitInfo));   
    }
