Hi!
When I register my own functions with gluTessCallback I have to cast them:
typedef void (__stdcall * TessFuncPtr)( );
gluTessCallback( …, (TessFuncPtr) …);
Otherwise I get a compilation error.
When I register library functions (eg. glBegin(), glVertex3dv(), …) I don’t have to cast it to get the code to compile.
As far as I can tell, my functions have exactly the same signature as the corresponding library function.
Can anyone please explain this to me?
Btw, I’m compiling with gcc/3.3.1 under Cygwin.
