rprMaterialNodeGetInputInfo

Queries information for a material node input.

rpr_status rprMaterialNodeGetInputInfo( rpr_material_node in_node,
  rpr_int in_input_idx,
  rpr_material_node_input_info in_info,
  size_t in_size,
  void * in_data,
  size_t * out_size);

Parameters

Parameter Description
in_node The material node to query.
in_input_idx The index of the material node input to query.
in_info The type of information requested.
size Size of buffer pointed to by data variable.
data The buffer into which query info will be placed.
size_ret Returns 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_node_input_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.
