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.

Notes

Query operations usually include two steps:

  1. 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.
  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.
