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_NONE.

The ov points to the array of origins. The nov specifies the number of origins included in ov.

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