.. function:: int nghttp2_session_consume(nghttp2_session *session, int32_t stream_id, size_t size)
Tells the *session* that *size* bytes for a stream denoted by
*stream_id* were consumed by application and are ready to
WINDOW_UPDATE. The consumed bytes are counted towards both
connection and stream level WINDOW_UPDATE (see
`nghttp2_session_consume_connection()` and
`nghttp2_session_consume_stream()` to update consumption
independently). This function is intended to be used without
automatic window update (see
`nghttp2_option_set_no_auto_window_update()`).
This function returns 0 if it succeeds, or one of the following
negative error codes:
:enum:`nghttp2_error.NGHTTP2_ERR_NOMEM`
Out of memory.
:enum:`nghttp2_error.NGHTTP2_ERR_INVALID_ARGUMENT`
The *stream_id* is 0.
:enum:`nghttp2_error.NGHTTP2_ERR_INVALID_STATE`
Automatic WINDOW_UPDATE is not disabled.
