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.
