Submits response HEADERS frame and optionally one or more DATA
frames against the stream |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 fields in |hfa|. It
also lower-cases all names in |hfa|. The order of elements in
|hfa| is preserved.
HTTP/2 specification has requirement about header fields in the
response HEADERS. See the specification for more details.
If |data_prd| is not null, it provides data which will be sent
in subsequent DATA frames. If |data_prd| is null, HEADERS will have
END_STREAM flag set.
This method can be used as normal HTTP response and push response.
When pushing a resource using this function, the Session must be
configured using new Session() or its variants and
the target stream denoted by the |stream_id| must be reserved using
submitPushPromise().
To send non-final response headers (e.g., HTTP status 101), don't
use this function because this function half-closes the outbound
stream. Instead, use submitHeaders() for this purpose.
This function returns 0 if it succeeds, or one of the following
negative error codes:
Calling this function twice for the same stream ID may lead to
program crash. It is generally considered to a programming error
to commit response twice.
