rprContextGetInfo

Queries the current context for information, such as buffer size.

rpr_status rprContextGetInfo(	rpr_context context,
	rpr_context_info context_info,
	size_t size,
	void * data,
	size_t * size_ret);

Parameters

Parameter	Description
context	The context to be queried.
context_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 rpr_context_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.
