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.

Query operations usually include two steps:

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.
Secondly, query with size_ret set to NULL to fill the data buffer with the query data.

Size in bytes of the data being queried.

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