SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_alloc_error(nng_http_res **resp, uint16_t status);DESCRIPTION
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".
| This is the simplest way to generate an error response. |
