我可以将一个对象的指针传递到共享内存吗?

我有一个非常复杂的类(它内部具有unordered_map等)，我想与我的两个进程共享该对象.我可以简单地将一个指向它的指针从一个进程传递到另一个进程吗?我认为不是，但是希望听到是！".

I have a very complicated class(it has unordered_map and so on on inside it) and I want to share an object of it withit two my processes. Can I simply pass just a pointer to it from one process to another? I think, no, but hope to hear "Yes!".

如果为否"，我将很高兴看到任何链接在这种情况下如何应对. 对于所有进程，我只需要有该对象的一个​​实例，因为它非常大，并且所有进程都可以正常工作，仅供只读.

If "no", I'd be grateful to see any links how to cope in such cases. I need to have only one instance of this object for all processes because it's very large and all of the processes will work woth it for read only.
