int nghttp2_submit_origin(nghttp2_session *session, uint8_t flags, const nghttp2_origin_entry *ov, size_t nov)

Submits ORIGIN frame.

ORIGIN frame is a non-critical extension to HTTP/2 and defined by RFC 8336.

The flags is currently ignored and should be nghttp2_flag.NGHTTP2_FLAG_NONE.

The ov points to the array of origins. The nov specifies the number of origins included in ov. This function creates copies of all elements in ov.

The ORIGIN frame is only usable by a server. If this function is invoked with client side session, this function returns nghttp2_error.NGHTTP2_ERR_INVALID_STATE.


Out of memory


The function is called from client side session.


There are too many origins, or an origin is too large to fit into a default frame payload.
