void *到C ++ / CLI中的Object ^ [英] void* to Object^ in C++/CLI

问题描述

我正在努力将大量的.h和.lib文件从本机C ++包装到托管C ++，最终用作C＃中引用的.dll。

I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#.

一些本机C ++函数的返回类型为void *。我不知道如何处理这个当我将值传递回我的调用代码。例如：如果一个C＃应用程序调用我的dll包装，我从本地调用返回：

Some of the native C++ functions have a return type of void*. I am not sure how to handle this when I pass back the value to my calling code. For instance: if a C# app calls my dll wrapper, what do I return from the native call:

void* start(ThreadFunc,void *, unsigned *);

我目前正试图在通用System :: Object ^这是包装器中的调用：

I am currently attempting to box the return in a generic System::Object^ with no luck. This is the call in the wrapper:

m_NativeThread->start(cb, 
        GCHandle::ToIntPtr(GCHandle::Alloc(o)).ToPointer(),
        static_cast<unsigned int*>(GCHandle::ToIntPtr(GCHandle::Alloc(u)).ToPointer())));

任何人都可以提供解决方案？

Can anyone offer a solution?

推荐答案

你能使它成为一个IntPtr吗？你期望客户对void *做什么？

Can you make it an IntPtr? What do you expect the client to do with the void*?
