void gluQuadricCallback( GLUquadric* quad,

                       GLenum which,
                       _GLUfuncptr CallBackFunc )

quad	Specifies the quadrics object (created with  gluNewQuadric).
which	Specifies the callback being defined. The only valid value is  GLU_ERROR.
CallBackFunc	Specifies the function to be called.

 gluQuadricCallback is used to define a new callback to be used by a quadrics object. If the specified callback is already defined, then it is replaced. If CallBackFunc is NULL, then any existing callback is erased.

The one legal callback is  GLU_ERROR:

GLU_ERROR	The function is called when an error is encountered. Its single argument is of type GLenum, and it indicates the specific error that occurred. Character strings describing these errors can be retrieved with the  gluErrorString call.
