gluQuadricCallback()                         gluQuadricCallback()

NAME    [Toc]    [Back]

       gluQuadricCallback  -  define  a  callback  for a quadrics
       object

SYNOPSIS    [Toc]    [Back]

       void gluQuadricCallback(
               GLUquadric* quad,
               GLenum which,
               GLvoid (*CallBackFunc) );

PARAMETERS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

       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:  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.
