| * \note Parameter tuning DOES depend on the order of the tuning parameters. E.g. some parameter |
| * update may allow some subsequent parameter update. |
| * |
| * This method MUST be "non-blocking" and return within 1ms. |
| * |
| * \param params a list of parameter updates. These will be updated to the actual |
| * parameter values after the updates (this is because tuning is performed |
| * at best effort). |
| * \todo params that could not be updated are not marked here, so are |
| * confusing - are they "existing" values or intended to be configured |
| * values? |
| * \param failures a list of parameter failures |
| * |
| * \retval C2_OK all parameters could be updated successfully |
| * \retval C2_BAD_INDEX all supported parameters could be updated successfully, but some |
| * parameters were not supported |
| * \retval C2_BAD_VALUE some supported parameters could not be updated successfully because |
| * they contained unsupported values. These are returned in |failures|. |
| * \retval C2_NO_MEMORY some supported parameters could not be updated successfully because |
| * they contained unsupported values, but could not allocate a failure |
| * object for them. |
| * \retval C2_CORRUPTED some unknown error prevented the update of the parameters |
| * (unexpected) |
