void
gluQuadricCallback( GLUquadric* quad,

eqn not supported
- 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.
