== NAME
nng_http_res_alloc - allocate HTTP response structure
== SYNOPSIS
[source, c]
-----------
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_alloc(nng_http_res **resp);
-----------
== DESCRIPTION
The `nng_http_res_alloc()` function allocates a new HTTP response structure
and stores a pointer to it in __resp__.
The response will be initialized
with status code 200 (`NNG_HTTP_STATUS_OK`), and a reason phrase of "OK",
and HTTP protocol version "HTTP/1.1".
TIP: When an error response is needed, consider using
<<nng_http_res_alloc_error.3http#,`nng_http_res_alloc_error()`>> instead.
== RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
== ERRORS
`NNG_ENOMEM`:: Insufficient free memory exists to allocate a message.
`NNG_ENOTSUP`:: HTTP support not configured.
