void gluTessCallback(GLUtesselator *tessobj, GLenum type, void (*fn)()); i must define something or just put names or what---- pls help me... i really need a simple example that works to understand

Please don't hurt the computer. :(

Okay, I uploaded an example for you, which was included in Red book source codes, "tess.c".
tess.zip (http://www.songho.ca/opengl/files/tess.zip)

I modified a little, so it can be compiled with C++, but all credits and rights go to OpenGL and SGI.

You will see 2 models on the screen: a rectangle with a hole in the middle, and a self-intersecting star shape.

I used g++ compiler with Dev-C++, but you can recompile it with any compiler by yourself.
