如何检测函数的调用线程是否已经是RTAI实时的？
我正在开发一个在内核和用户空间都使用 RTAI 的大项目。我不会详细介绍该项目，但这里简要介绍一下出现问题的地方。
在用户空间中，我的项目提供了一个供其他人用来编写一些软件的库。这些程序本身可能具有 RTAI 实时线程。
现在，RTAI 中的一些函数要求它们的调用线程已经 rt_thread_inited，因此如果我想在库中的函数中使用它们，我需要通过调用 <代码>rt_thread_init和后来的rt_task_delete。
现在的问题是：
如果我的函数的调用线程已经是实时的，那么我正在 rt_thread_initing，我认为它会失败，但随后我 rt_task_delete 并使其成功线程非实时（除了当线程本身（假设我没有更改任何内容）再次rt_task_deletes时，RTAI崩溃。
如果我的函数的调用线程不是实时的， 现在一切都很好，
我在函数中采用了一个参数，以便调用函数告诉库它是否是实时的，但是，我想知道 RTAI 是否有一个函数或其他东西。我可以用来自动检测当前线程是否实时。
不知道这里是否有 RTAI 用户（我当然没有看到 RTAI 标签），但希望会有。
I am working on a big project that uses RTAI both in kernel and user spaces. I won't get into the details of the project, but here is briefly where a problem arises.
In user-space, my project provides a library used by other people to write some software. Those programs themselves may have RTAI real-time threads.
Now, some functions in RTAI require that their calling thread have already rt_thread_inited so if I want to use them in a function in the library, I need to temporarily make the calling thread real-time by calling rt_thread_init and later rt_task_delete.
Now here's the problem:
If the calling thread of my function IS already real-time, then I am rt_thread_initing which I assume simply fails, but then I rt_task_delete and make that thread non-real-time (besides the fact that when the thread itself (assuming I changed nothing) again rt_task_deletes, RTAI crashes.
If the calling thread of my function IS not real-time, everything is ok.
For now, I resorted to taking a parameter in the function so that the calling function tells the library if it is real-time or not. However, I wanted to know if RTAI has a function or something so I could use to automatically detect whether the current thread is real-time or not.
Don't know if there are any RTAI users here (I certainly didn't see the RTAI tag), but hope there would be.

我自己从未尝试过，所以这是一个猜测 - 但你考虑过使用 rt_whoami 吗？

我想如果你处于非 RT 任务中它会失败（返回 NULL？）...
Never tried it myself, so this is a guess - but did you consider using rt_whoami?

I would imagine it will fail (return NULL?) if you are in a non RT task...
