The |stream_id| must be client initiated stream ID.
The |hfa| is an array of HeaderField with
|hfa.length| elements. The application is responsible to include
required pseudo-header fields (header field whose name starts with
":") in |hfa| and must place pseudo-headers before regular header
fields.
This function creates copies of all header fieldss in |hfa|. It
also lower-cases all names in |hfa|. The order of elements in
|hfa| is preserved.
The |promised_stream_user_data| is a pointer to an arbitrary data
which is associated to the promised stream this frame will open and
make it in reserved state. It is available using Session.getStreamUserData.
The application can access it in Connector.onFrameHeader and
Connector.onFrameSent of this frame.
The client side is not allowed to use this function.
To submit response headers and data, use
submitResponse().
This function returns assigned promised stream ID if it succeeds,
or one of the following negative error codes:
This function returns assigned promised stream ID if it succeeds.
But that stream is not opened yet. The application must not
submit frame to that stream ID before
Connector.onFrameHeader is called for this
frame.
