gluTessCallback Problem

OpenGL OpenGL: Basic Coding
1

Hello,

I am trying to get gluTessCallback to start working, but every time I try to execute my program it keep giving me an error that looks like this:

error C2664: ‘gluTessCallback’ : cannot convert parameter 3 from ‘void (unsigned int)’ to ‘void (__stdcall *)(void)’

Has anyone had this problem before, and is there a way to fix it?

Edit: I also have this in my code.

#include <GL/glu.h>
#pragma comment( lib, “glu32.lib”)

gluTessCallback(tobj, GLU_TESS_BEGIN, glBegin);
gluTessCallback(tobj, GLU_VERTEX, glVertex2fv);
gluTessCallback(tobj, GLU_END, glEnd);

Just cast the function pointer to proper type.

gluTessCallback(tobj, GLU_TESS_BEGIN, reinterpret_cast<void (__stdcall *)(void)>(glBegin));

Thank you very much Bob, it is working now!!!
