Radeon ProRender


Queries information about a context parameter.

rpr_status rprContextGetParameterInfo( rpr_context context,
  int param_idx,
  rpr_parameter_info parameter_info,
  size_t size,
  void * data,
  size_t * size_ret);


Parameter Description
context The context to query.
param_idx The index of the parameter. Value must be between 0 and (value stored in RPR_CONTEXT_PARAMETER_COUNT) -1.
parameter_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 Returns the size in bytes of the data being queried.


Query operations usually include two steps:

  1. First, pass data as NULL along with a value for rpr_parameter_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.


Size in bytes of the data being queried.


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