CefResponseFilterFilter Method

Called to filter a chunk of data. |data_in| is the input buffer containing |data_in_size| bytes of pre-filter data (|data_in| will be NULL if |data_in_size| is zero). |data_out| is the output buffer that can accept up to |data_out_size| bytes of filtered output data. Set |data_in_read| to the number of bytes that were read from |data_in|. Set |data_out_written| to the number of bytes that were written into |data_out|. If some or all of the pre-filter data was read successfully but more data is needed in order to continue filtering (filtered output is pending) return RESPONSE_FILTER_NEED_MORE_DATA. If some or all of the pre-filter data was read successfully and all available filtered output has been written return RESPONSE_FILTER_DONE. If an error occurs during filtering return RESPONSE_FILTER_ERROR. This method will be called repeatedly until there is no more data to filter (resource response is complete), |data_in_read| matches |data_in_size| (all available pre-filter bytes have been read), and the method returns RESPONSE_FILTER_DONE or RESPONSE_FILTER_ERROR. Do not keep a reference to the buffers passed to this method.
