C SPECIFICATION

10       void gluQuadricCallback( GLUquadric* quad,
11                                GLenum which,
12                                _GLUfuncptr CallBackFunc )

PARAMETERS

16       quad          Specifies    the    quadrics    object    (created   with
17                     gluNewQuadric).
18
19       which         Specifies the callback being  defined.   The  only  valid
20                     value is GLU_ERROR.
21
22       CallBackFunc  Specifies the function to be called.

DESCRIPTION

25       gluQuadricCallback  is  used  to  define a new callback to be used by a
26       quadrics object.  If the specified callback is already defined, then it
27       is  replaced.  If  CallBackFunc  is NULL, then any existing callback is
28       erased.
29
30       The one legal callback is GLU_ERROR:
31
32       GLU_ERROR      The function is called when an error is encountered. Its
33                      single  argument is of type GLenum, and it indicates the
34                      specific  error  that   occurred.    Character   strings
35                      describing  these  errors  can  be  retrieved  with  the
36                      gluErrorString call.
