hi,

I am trying to implement traverser callbacks in a c++ class. If I try to
make the function a member function, I get this error:

"NelAircraft.cpp", line 333: error(1515): a value of type
          "void (NelAircraft::*)(pfuTraverser *)" cannot be assigned to an
          entity of type "pfuTravFuncType"
      trav.preFunc = foo_preTravCB;
                   ^

if I prototype the functions separately:

        int foo_postTravCB(pfuTraverser *trav);

then I compile with no problem. How am I supposed to write this to
get the c++ compiler to be happy?

thanks

ken
