NAME
nng_http_res_alloc_error - allocate HTTP error response
SYNOPSIS
DESCRIPTION

and stores a pointer to it in resp.

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".
| This is the simplest way to generate an error response. |
