nghttp2_session_consume ======================= Synopsis -------- *#include * .. 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.
