rprHeteroVolumeGetInfo

Queries information about a heterogenous volume.

rpr_status rprHeteroVolumeGetInfo(	rpr_hetero_volume heteroVol,
	rpr_hetero_volume_parameter heteroVol_info,
	size_t size,
	void * data,
	size_t * size_ret);

Parameters

Parameter	Description
heteroVol	The heterogenous volume to query.
heteroVol_info	The type of info to query.
size	The size of the buffer pointed by data.
data	The buffer to store queried info.
size_ret	Gives 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_hetero_volume_parameter 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 data being queried.

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