It works the same, cast the data you receive to a TMethod and call the
"code" member with the appropriate parameters. So, in the "C" library do
void SetHandler(TMethod h);
StoredH = h;
typedef void (*TDataHandler)(void* Self, void* Data);
Warning, this is pseudo code, you should adapt it so that it can compile.
