fglGetListParameterSGIX(3G)

NAME
     fglGetListParameterfvSGIX, fglGetListParameterivSGIX - retrieve display
     list parameters


FORTRAN SPECIFICATION
     SUBROUTINE fglGetListParameterfvSGIX( INTEGER*4 list,
                                           INTEGER*4 pname,
                                           CHARACTER*8 params )
     SUBROUTINE fglGetListParameterivSGIX( INTEGER*4 list,
                                           INTEGER*4 pname,
                                           CHARACTER*8 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
             GL_LIST_PRIORITY_SGIX.

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

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

     The returned value lies in the range [0.0, 1.0]. If
     fglGetListParameterivSGIX 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.

     fglGetListParameterSGIX is not included in display lists.

NOTES
     fglGetListParameterSGIX is part of the SGIX_list_priority extension.  See
     fglIntro for more information about using extensions.

ERRORS
     GL_INVALID_VALUE is generated if the parameter list is 0.

     GL_INVALID_ENUM is generated if the paramter pname is not one of the
     accepted values.
     GL_INVALID_OPERATION is generated if fglGetListParameterSGIX is executed
     between the execution of fglBegin and the corresponding execution of
     fglEnd.
