Hi Linh,
Did you try:
#include
#include
void test (void)
{
GLUtesselator *tobj = gluNewTess();
gluTessCallback(tobj, (GLenum)GLU_BEGIN, glBegin);
gluTessCallback(tobj, (GLenum)GLU_END, glEnd);
gluTessCallback(tobj, (GLenum)GLU_VERTEX, glVertex2fv);
}
Anyway, glu.h shows that the prototype for gluTessCallback is:
GLAPI void APIENTRY gluTessCallback (GLUtesselator* tess, GLenum which,
_GLUfuncptr CallBackFunc);
so (_GLUfuncptr) is the obvious cast, no?
