工作CreateJobObject / SetInformationJobObject的PInvoke在.NET的例子吗？

问题描述

我挣扎放在一起pinvoke'ing CreateJobObject和SetInformationJobObject的工作示例。通过各种谷歌搜索（包括俄罗斯和中国的职位！）我拼凑以下code。我认为，基于平台的JOBOBJECT_BASIC_LIMIT_INFORMATION变化定义（六十四分之三十二位）。该CreateJobObject / AssignProcessToJobObject的似乎的工作。 SetInformationJobObject失败 - 无论是与错误24或87。

解决方案

这可能是有点晚了，但仍。

我尝试了所有在这里的例子，但没有人是在32位和64位模式，同时为我工作。最后，我被要求检查所有的签名，自己并创建相应的PInvoke程序。我想，别人可能会有所帮助。

I'm struggling to put together a working example of pinvoke'ing CreateJobObject and SetInformationJobObject. Through various google searches (including Russian and Chinese posts!) I've cobbled together the following code. I think the definition of JOBOBJECT_BASIC_LIMIT_INFORMATION changes based on platform (32/64-bit). The CreateJobObject/AssignProcessToJobObject seems to work. SetInformationJobObject fails - either with error 24 or 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 ) )
...

解决方案

This can be little bit late, but still.

I tried all of the examples here, but no one was working for me in 32 and 64 bit mode simultaneously. Finally, I was required to examine all the signatures myself and create corresponding PInvoke routines. I think, somebody else could find this helpful.
