有哪些＆QUOT;好＆QUOT;方法使用的longjmp对于C错误处理/ setjmp的？

我必须使用下一个项目，我用的longjmp / setjmp的处理错误的思想，因为我认为这将是更容易在一个*处理错误地方不是返回codeS。我想AP preciate如果有关于如何做到这一些线索。

I have to use C for one project and I am thinking of using longjmp/setjmp for error handling as I think it will be much easier to handle error in one central place than return codes. I would appreciate if there are some leads on how to do this.

我特别关注，如果发生任何此类错误资源清理被正确完成。

I am particularly concerned with resource cleanup being correctly done if any such error occurs.

另外我该如何处理使用他们，导致多线程程序错误？

Also how do I handle errors that result in multi-threaded programs using them?

更妙的是，有没有已经存在的错误/异常处理一些C库？

Even better, is there some C library that already exists for error/exception handling?
