guys , i'm still with doubts... but not more about c#, now about c++ i was thinking about rewrite the code with c++ my doubt is.... could i use C++ 11 ? or i will have problem with mariadb makefiles etc etc? 2015-09-18 1:40 GMT-03:00 Roberto Spadim <roberto@spadim.com.br>:
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,
--Justin

Hi, Roberto!
Hi guys, I have a program wrote in c#, it process some code and the result is a struct (an array of string/double/int) I want to include this program inside mariadb server as a daemon

process data) + a storage engine (to read struct data)
is that possible? considering that i can write dll with .net? what about write this to linux (.so files) ?
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.
