== NAME
nng_http_res_set_reason - set HTTP response reason
== SYNOPSIS
[source, c]
----
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_set_reason(nng_http_res *res, const char *reason);
----
== DESCRIPTION
The `nng_http_res_set_reason()` sets the human readable reason
associated with the response _res_ to _reason_.
If the value of _reason_ is `NULL` (the default), then a default reason
phrase is supplied based upon the value of the status code (see
xref:nng_http_res_set_status.3http.adoc[`nng_http_res_set_status()`]).
TIP: The _reason_ is never parsed automatically, but it can be a hint for humans
to help them understand the nature of any erroneous result.
A local copy of the _reason_ is made in the response _res_.
== RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
== ERRORS
[horizontal]
`NNG_ENOMEM`:: Insufficient memory to perform the operation.
`NNG_ENOTSUP`:: No support for HTTP in the library.
