rprMaterialSystemGetInfo

Queries details for a particular material system.

rpr_status rprMaterialSystemGetInfo( rpr_material_system in_material_system,
  rpr_material_system_info type,
  size_t in_size,
  void * in_data,
  size_t * out_size);

Parameters

Parameter Description
in_material_system The material system to query.
type The information to obtain.
in_size Size of the buffer pointed to by the data variable.
in_data A buffer into which the results of the query will be stored.
out_size Retuns the size in bytes of the data being queried.

Notes

Query operations usually include two steps:

  1. First, pass data as NULL along with a value for rpr_material_system_info 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.

Output

Size in bytes of the data being queried.

Return

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