SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
void nng_http_conn_write_res(nng_http_conn *conn, nng_http_res *res,
nng_aio *aio);DESCRIPTION
The nng_http_conn_write_res() function starts an asynchronous write of
the HTTP response res to the connection conn.
The entire response is sent,
including headers, and if present, the response body data.
(The response body can be set with
nng_http_res_set_data() or
nng_http_res_copy_data().)
This function returns immediately, with no return value.
Completion of the operation is signaled via the aio, and the final result
may be obtained via nng_aio_result().
That result will either be zero or an error code.
Persistent Connections
By default, for HTTP/1.1 connections, the connection is kept open, and
will be reused to receive new requests.
If however the res contains a header of Connection: with a value
of Close (case-insensitive) or the response corresponds to HTTP/1.0,
then the connection is immediately after sending the response.
RETURN VALUES
None.
