Q3NURBCurve_GetData
You can use the Q3NURBCurve_GetData function to get the data that defines a NURB curve and its attributes.
TQ3Status Q3NURBCurve_GetData (
TQ3GeometryObject curve, 
TQ3NURBCurveData *nurbCurveData); 
curve
A NURB curve.
nurbCurveData
On exit, a pointer to a TQ3NURBCurveData structure that contains information about the NURB curve specified by the curve parameter.

DESCRIPTION
The Q3NURBCurve_GetData function returns, through the nurbCurveData parameter, information about the NURB curve specified by the curve parameter. QuickDraw 3D allocates memory for the TQ3NURBCurveData structure internally; you must call Q3NURBCurve_EmptyData to dispose of that memory.
