int nng_http_res_alloc_error(nng_http_res **resp, uint16_t status);The nng_http_res_alloc_error() function allocates a new HTTP response structure
and stores a pointer to it in resp.
The response will be initialized
with the status code status, a corresponding reason phrase, and
a simple HTML page containing the same information will be generated and
attached to the response.
(Relevant HTTP headers will be set as well, such as Content-Type
and Content-Length.)
The HTTP protocol version is also set to "HTTP/1.1".
