rprCompositeGetInfo

Queries rpr_composite node for information.

rpr_status rprCompositeGetInfo(	rpr_composite composite,
	rpr_composite_info composite_info,
	size_t size,
	void * data,
	size_t * size_ret);,

Parameters

Parameter	Description
composite	The composite node to be queried.
composite_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 composite_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.
