Radeon ProRender


Queries information about a curve.

rpr_status rprCurveGetInfo( rpr_curve curve,
  rpr_curve_parameter curve_info,
  size_t size,
  void * data,
  size_t * size_ret);


Parameter Description
curve The curve to query.
curve_info The type of info to query.
size The size of the buffer pointed by the data variable.
data A buffer into which the results of the query will be stored.
size_ret Returns the size in bytes of the data being queried.


Query operations usually include two steps:

  1. First, pass data as NULL along with a value for rpr_curve_parameter detailing the information you wish to obtain. This will return the storage requirements for your query data.
  2. Secondly, query with size_ret set to NULL to fill the data buffer with the query data.



Returns RPR_SUCCESS in case of success, or RPR_ERROR code if a problem was encountered.
