int nghttp2_session_set_next_stream_id(nghttp2_session *session, int32_t next_stream_id)

Tells the session that next stream ID is next_stream_id. The next_stream_id must be equal or greater than the value returned by nghttp2_session_get_next_stream_id().

This function returns 0 if it succeeds, or one of the following negative error codes:

The next_stream_id is strictly less than the value nghttp2_session_get_next_stream_id() returns; or next_stream_id is invalid (e.g., even integer for client, or odd integer for server).
