SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_copy_data(nng_http_res *res, const void *body, size_t size);DESCRIPTION
The nng_http_res_copy_data() makes a copy of body (of size size)
and sets the HTTP body for the response res to it. The copy will be
deallocated automatically when res is freed.
The copied body data will be automatically sent with the response when it is sent using nni_http_conn_write_res(3).
This also updates the relevant Content-Length header of res.
| The current framework does not support sending data via chunked transfer-encoding. |
| To avoid copying data, the nng_http_res_set_data(3) may be used instead. |
It is a good idea to also set the Content-Type header.
