.. function:: int nghttp2_session_upgrade(nghttp2_session *session, const uint8_t *settings_payload, size_t settings_payloadlen, void *stream_user_data)
Performs post-process of HTTP Upgrade request. This function can be
called from both client and server, but the behavior is very
different in each other.
If called from client side, the *settings_payload* must be the
value sent in HTTP2-Settings header field and must be decoded by
base64url decoder. The *settings_payloadlen* is the length of
*settings_payload*. The *settings_payload* is unpacked and its
setting values will be submitted using
nghttp2_submit_settings(). This means that the client application
code does not need to submit SETTINGS by itself. The stream with
stream ID=1 is opened and the *stream_user_data* is used for its
stream_user_data. The opened stream becomes half-closed (local)
state.
If called from server side, the *settings_payload* must be the
value received in HTTP2-Settings header field and must be decoded
by base64url decoder. The *settings_payloadlen* is the length of
*settings_payload*. It is treated as if the SETTINGS frame with
that payload is received. Thus, callback functions for the
reception of SETTINGS frame will be invoked. The stream with stream
ID=1 is opened. The *stream_user_data* is ignored. The opened
stream becomes half-closed (remote).
This function returns 0 if it succeeds, or one of the following
negative error codes:
:macro:`NGHTTP2_ERR_NOMEM`
Out of memory.
:macro:`NGHTTP2_ERR_INVALID_ARGUMENT`
The *settings_payload* is badly formed.
:macro:`NGHTTP2_ERR_PROTO`
The stream ID 1 is already used or closed; or is not available;
or the *settings_payload* does not include both
NGHTTP2_SETTINGS_MAX_CONCURRENT_STREAMS and
NGHTTP2_SETTINGS_INITIAL_WINDOW_SIZE.
.. function:: ssize_t nghttp2_pack_settings_payload(uint8_t *buf, nghttp2_settings_entry *iv, size_t niv)
Serializes the SETTINGS values *iv* in the *buf*. The number of
entry pointed by *iv* array is given by the *niv*. This function
may reorder the pointers in *iv*. The *buf* must have enough region
to hold serialized data. The required space for the *niv* entries
are 8**niv* bytes. This function is used mainly for creating
SETTINGS payload to be sent with HTTP2-Settings header field in
HTTP Upgrade request. The data written in *buf* is not still
base64url encoded and the application is responsible to do that.
This function returns the number of bytes written in *buf*, or one
of the following negative error codes:
:macro:`NGHTTP2_ERR_INVALID_ARGUMENT`
The *iv* contains duplicate settings ID or invalid value.
