NAME
       gluQuadricCallback - define a callback for a quadrics object

C SPECIFICATION
       void gluQuadricCallback( GLUquadric* quad,
				GLenum which,
				_GLUfuncptr CallBackFunc )

PARAMETERS
       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.

DESCRIPTION
       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.
