glGetListParameterSGIX(3G)     OpenGL Reference     glGetListParameterSGIX(3G)



NAME
     glGetListParameterfvSGIX, glGetListParameterivSGIX - retrieve display
     list parameters


C SPECIFICATION
     void glGetListParameterfvSGIX( GLuint list,
                                    GLenum pname,
                                    GLfloat *params )
     void glGetListParameterivSGIX( GLuint list,
                                    GLenum pname,
                                    GLint *params )


PARAMETERS
     list    Specifies the integer name of the display list whose parameters
             are to be retrieved.

     pname   Specifies the symbolic name for display list parameter. Must be
             GLLISTPRIORITYSGIX.

     params  Specifies a pointer to an array in which parameter values will be
             stored.  If pname is GLLISTPRIORITYSGIX, then the array must
             have at least one element.

DESCRIPTION
     glGetListParameterSGIX returns the values for parameter pname associated
     with the display list named list. Currently, pname must be
     GLLISTPRIORITYSGIX, in which case the display list priority is
     retrieved in params.

     The returned value lies in the range [0.0, 1.0]. If
     glGetListParameterivSGIX is used to retrieve list priority, the returned
     value is rounded to 0 or 1.

     If the parameter list does not refer to a valid list, the return value in
     params is undefined.

     glGetListParameterSGIX is not included in display lists.

NOTES
     glGetListParameterSGIX is part of the SGIXlistpriority extension.  See
     glIntro for more information about using extensions.

ERRORS
     GLINVALIDVALUE is generated if the parameter list is 0.

     GLINVALIDENUM is generated if the paramter pname is not one of the
     accepted values.

     GLINVALIDOPERATION is generated if glGetListParameterSGIX is executed
     between the execution of glBegin and the corresponding execution of
     glEnd.
