[Boost-users] function/bind - passing function pointer to C API

Hi, I am attempting to use Boost bind and function to help me pass a member function as a function pointer to the GLUT C-library. I have difficulty understanding the usage of bind and function in the Boost library. When I attempt to pass what I thought was a function pointer, the compiler indicated that it is actually not a function pointer. class MyGlut { public: MyGlut(); virtual ~MyGlut(); void loop(int argc, char **argv); void draw(void); void displayFunc(boost::function func); private: boost::function display_callback; }; void MyGlut::displayFunc(boost::function func) { glutDisplayFunc(func); // ERROR IN COMPILATION } void MyGlut::loop(int argc, char **argv) { glutInit(&argc,argv); glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH | GLUT_MULTISAMPLE); glutCreateWindow("Hello World"); //glutDisplayFunc(redraw); // Original way to pass C-function pointer displayFunc( boost::bind(&MyGlut::draw, *this) ); } Regards
