how to pass a callback function from the c# code into a function in C++ CLR ? If I add a parameter to the callback function once it becomes invisible to my code in c#

//c++ clr
typedef int (__stdcall * Callback)(int*, int,int);

bool Init() //<-- OK
{
}

bool Init(Callback cb)//<-- Init is not visible to my code in c#
{

}

I plan to call this callback from another thread. I have experience with callback for unmanaged DLL , but for the CLR does not understand how to do.

if you use c++/cli why don't you just declare a delegate instead of C function pointer? – Zdeslav Vojkovic Mar 19 '13 at 15:33

A delegate of `System.Func` or similar – sehe Mar 19 '13 at 15:34
