我有一个Win32 C++应用程序。我试图用CreateProcess启动一个或多个子进程。我希望在父进程关闭时关闭子进程。
我通过创建一个作业并启用JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE来实现这一点：

HANDLE hJob = CreateJobObject(NULL, NULL);

JOBOBJECT_EXTENDED_LIMIT_INFORMATION extendedInfo;
ZeroMemory(&extendedInfo, sizeof(extendedInfo));
extendedInfo.BasicLimitInformation.LimitFlags =
    JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE;

SetInformationJobObject(
        hJob, JOBOBJECTINFOCLASS::JobObjectExtendedLimitInformation,
        &extendedInfo, sizeof(extendedInfo));

然后将当前（父）和创建的（子）流程添加到此作业：

// assign parent to job
AssignProcessToJobObject(hJob, GetCurrentProcess());

// launch child with no inherited handles
PROCESS_INFORMATION procInfo;
ZeroMemory(&procInfo, sizeof(procInfo));
STARTUPINFOA startInfo;
ZeroMemory(&startInfo, sizeof(startInfo));
startInfo.cb = sizeof(startInfo);
startInfo.dwFlags |= STARTF_USESTDHANDLES;
bool success = CreateProcessA(NULL,
                              "test.exe",  // command line
                              NULL,     // process security attributes
                              NULL,   // primary thread security attributes
                              FALSE,  // handles are inherited
                              0,      // creation flags
                              NULL,   // use parent's environment
                              NULL,   // use parent's current directory
                              &startInfo,  // STARTUPINFO pointer
                              &procInfo);  // receives PROCESS_INFORMATION
// assign child to job
AssignProcessToJobObject(hJob, procInfo.hProcess);

这是可行的，但父应用和子应用（main.exe和test.exe）在任务管理器中显示为两个不相关的进程：

(Even尽管关闭main.exe将关闭test.exe）。
我的做法与微软团队或Chrome有什么不同，它们都有嵌套的进程？
