Hi all!

yes justin, probably a c++ and a c# interface 

well next weeks maybe i will start some tests :)

thanks a lot for a first direction, i was looking about pinvoke, etc etc, like mysqld/mariadb do at plugins :)

Hi,

You could try:

class DaemonPlugin

{

  [DllExport("add",CallingConvention = CallingConvention.Cdecl)]

  public static int add(int left, int right)

  {

     return left + right;

  } 

}

Then write a C++ wrapper around the exported classes.  I don't think C# will be able to handle the pointers from the MySQL plugin API (or to do so would be tremendously cumbersome) so a wrapper around the .NET exported .NET code which handles the C memory management, etc, needed for a plugin will work best.  

I don't know much about this.  I learned the above from a few google searches, but hopefully it will get you going in the right direction.

Regards,

I think it's possible, why not? You might need a thin layer of the
interface code in C (seeing your code, I believe you can do that easily :),
and the main logic in C#. On Linux you can, perhaps, use Mono.

But I haven't heard of anyone doing that, so I don't know of any
specific pitfalls that you might face on this way.

Regards,
Sergei
