- * them in |buf| and return number of data stored in |buf|.  If EOF is
- * reached, set :enum:`NGHTTP2_DATA_FLAG_EOF` flag in |*data_flags|.
- *
- * Sometime it is desirable to avoid copying data into |buf| and let

- * :enum:`NGHTTP2_DATA_FLAG_NO_COPY` to |*data_flags| (and possibly
- * other flags, just like when we do copy), and return the number of
- * bytes to send without copying data into |buf|.  The library, seeing
- * :enum:`NGHTTP2_DATA_FLAG_NO_COPY`, will invoke
- * :type:`nghttp2_send_data_callback`.  The application must send
- * complete DATA frame in that callback.
- *
- * If this callback is set by `nghttp2_submit_request()`,

- * frame will have END_STREAM flag set.  Usually, this is expected
- * behaviour and all are fine.  One exception is send trailer fields.
- * You cannot send trailer fields after sending frame with END_STREAM
- * set.  To avoid this problem, one can set
- * :enum:`NGHTTP2_DATA_FLAG_NO_END_STREAM` along with
- * :enum:`NGHTTP2_DATA_FLAG_EOF` to signal the library not to set
- * END_STREAM in DATA frame.  Then application can use
- * `nghttp2_submit_trailer()` to send trailer fields.
- * `nghttp2_submit_trailer()` can be called inside this callback.
- *
- * If the application wants to postpone DATA frames (e.g.,
- * asynchronous I/O, or reading data blocks for long time), it is
- * achieved by returning :enum:`NGHTTP2_ERR_DEFERRED` without reading
- * any data in this invocation.  The library removes DATA frame from
- * the outgoing queue temporarily.  To move back deferred DATA frame
- * to outgoing queue, call `nghttp2_session_resume_data()`.  In case
- * of error, there are 2 choices. Returning
- * :enum:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE` will close the stream
- * by issuing RST_STREAM with :enum:`NGHTTP2_INTERNAL_ERROR`.  If a
- * different error code is desirable, use
- * `nghttp2_submit_rst_stream()` with a desired error code and then
- * return :enum:`NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE`.  Returning
- * :enum:`NGHTTP2_ERR_CALLBACK_FAILURE` will signal the entire session
