Я изо всех сил пытаюсь собрать работающий пример pinvoke'ing CreateJobObject и SetInformationJobObject. Посредством различных поисков в Google (включая сообщения на русском и китайском языках!) Я собрал следующий код. Я думаю, что определение JOBOBJECT_BASIC_LIMIT_INFORMATION изменяется в зависимости от платформы (32/64-разрядная версия). CreateJobObject / AssignProcessToJobObject кажется для работы. Ошибка SetInformationJobObject - либо с ошибкой 24, либо с 87.
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 );
SetInformationJobObject( job , JOBOBJECTINFOCLASS.JobObjectBasicLimitInformation , pionterToJobLimitInfo , ( uint )Marshal.SizeOf( limits ) )
