  // @scpi_response_helper
  // Helper function. Helps to implement correct data output from the QUERY.
  // Copies the query data and updates the @sRead.nDataLength and @common_ctx->status
  // to the appropriate values, also returns actual query data offset.
  // @common_ctx - common context pointer passed to the handler;
  // @idx - current data offset in the handler;
  // @source - the data source pointer;
  // @source_max - maximum length of @source
  // @isdone - optional, if passed, specifies wheither to set DONE status or not;
  // Returns: actual data offset for the handler after the data pushed into the output buffer
