rprMeshGetInfo

Queries details for a particular mesh.

rpr_status rprMeshGetInfo(	rpr_shape mesh,
	rpr_mesh_info mesh_info,
	size_t size,
	void * data,
	size_t * size_ret);

Parameters

Parameter	Description
mesh	The mesh to query.
mesh_info	The information 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	Retuns 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_mesh_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.
