Callback function

[f.vanalmetelevic.com]

Hi,

I'm currently adding voip-functionality to our Qt based application. This is a C-library that uses callback functionality to report back status information. I wonder what would be the best practice to get this in Qt code ? I assume I can't pass a class member function as a callback funtion pointer. I tried to set the class member function to static, but I get an error when building.
Do I have to mix C-code and C++ code to make this work ?
Any example would be great.

Thanks in advance.

If your static class member function match the declaration of your C library callback, then there should be no problem in your code.

As stated in the cpp faq, this includes the calling convention (cdecl, stdcall, that sorta thing).
