Using swig to use an existing dll/library

[peter.o.mueller]

Hi together,

i have a Windows DLL in C that is internally multithreaded and provides
a callback function to signal specific events. As I understood one can
use "normal" C-code with swig. Is it also possible to use existing
DLLs? Does swig can also handel the callback method? If not - is there
another wrapper toolkit that can do that?

Thanks,
Peter
