nghttp2_session_consume

Synopsis

#include <nghttp2/nghttp2.h>

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:

NGHTTP2_ERR_NOMEM
Out of memory.
NGHTTP2_ERR_INVALID_ARGUMENT
The stream_id is 0.
NGHTTP2_ERR_INVALID_STATE
Automatic WINDOW_UPDATE is not disabled.
