.net에서 CreateJobObject / SetInformationJobObject pinvoke의 작업 예제?

CreateJobObject 및 SetInformationJobObject를 pinvoke하는 작업 예제를 작성하는 데 어려움을 겪고 있습니다. 다양한 Google 검색 (러시아어 및 중국어 게시물 포함!)을 통해 다음 코드를 조합했습니다. JOBOBJECT_BASIC_LIMIT_INFORMATION의 정의는 플랫폼 (32/64 비트)에 따라 달라집니다. CreateJobObject / AssignProcessToJobObject 가 작동하는 것처럼 . SetInformationJobObject가 실패합니다. 오류 24 또는 87로 인해 실패합니다.

Process myProcess // POPULATED SOMEWHERE ELSE

// Create Job & assign this process and another process to the job
IntPtr jobHandle = CreateJobObject( null , null );
AssignProcessToJobObject( jobHandle , myProcess.Handle );
AssignProcessToJobObject( jobHandle , Process.GetCurrentProcess().Handle );

// Ensure that killing one process kills the others                
JOBOBJECT_BASIC_LIMIT_INFORMATION limits = new JOBOBJECT_BASIC_LIMIT_INFORMATION();
limits.LimitFlags = (short)LimitFlags.JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE;
IntPtr pointerToJobLimitInfo = Marshal.AllocHGlobal( Marshal.SizeOf( limits ) );
Marshal.StructureToPtr( limits , pointerToJobLimitInfo , false );
