NAME

nng_http_server_res_error - use HTTP server error page

SYNOPSIS

#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

int nng_http_server_res_error(nng_http_server *server,
        nng_http_res *response);

DESCRIPTION

The nng_http_server_res_error() sets the body of response to server's error page, which may have been customized using the nng_http_server_error_file() or nng_http_server_error_page() functions.

The status code of the response should have already been set, either implicitly by allocating it with nng_http_res_alloc_error(), or by calling nng_http_res_set_status().

Any content body previously set for response will be overridden by this function.

RETURN VALUES

This function returns 0 on success, and non-zero otherwise.

ERRORS

`NNG_ENOMEM`	Insufficient free memory exists.
`NNG_ENOTSUP`	HTTP not supported.
