== DESCRIPTION
|
|
|
|
The `nng_http_server_res_error()` sets the body of _response_
|
|
to _server_'s error page, which may have been customized using the
|
|
xref:nng_http_server_set_error_file.3http.adoc[`nng_http_server_error_file()`]
|
|
or
|
|
xref:nng_http_server_set_error_page.3http.adoc[`nng_http_server_error_page()`]
|
|
functions.
|
|
|
|
The status code of the _response_ should have already been set, either
|
|
implicitly by allocating it with
|
|
xref:nng_http_res_alloc_error.3http.adoc[`nng_http_res_alloc_error()`],
|
|
or by calling
|
|
xref:nng_http_res_set_status.3http.adoc[`nng_http_res_set_status()`].
|
|
|
|
Any content body previously set for _response_ will be overridden by
|
|
this function.
|
|
|
|
