rprCameraGetInfo

Queries details for a camera.

rpr_status rprCameraGetInfo( rpr_camera camera,
  rpr_camera_info camera_info,
  size_t size,
  void * data, size_t * size_ret);

Parameters

Parameter Description
camera The camera to query.
camera_info The information we wish to obtain.
size Size of the buffer pointed to by the data variable.
data A buffer into which the results of the query will be stored.
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 camera_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

The 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.
