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.
