fglGetListParameterSGIX(3G) OpenGL Reference 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.
