Thanks, so much. Does doing this, mean that my file CWBoonPlugin.cpp will have assess to both YADE functions like interaction->id1 and state->pos, as well as the external C library? In other words, behave like any other Ig2Functor?
Another question is this: The subroutine for the library is Minimize(a,b,C). C is again another subroutine C(x,y,z), which returns the value of the function and its derivatives. I cannot pass YADE pointers to it, because I cannot define C as C(x,y,z, yade pointer). I managed to do it in python by using "from yade import *". This way, I can assess O.bodies.state.pos any place I like within the subroutine, without giving it as the input argument. But the python one is running too slow. How do I do that in C/C++. The equivalent of "from yade import *"?
