SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
int nng_http_res_set_header(nng_http_res *res, const char *key,
const char *val);DESCRIPTION
The nng_http_res_set_header() sets the HTTP header for the response
res and the key to the val.
The key and val are copied.
Any previous header with the same key is replaced.
See nng_http_res_add_header() to
add additional headers with the same key without replacing them.
|
The value of key is case insensitive, and should not include the final
colon in an HTTP header.
For example, specifying Host or hOSt are
equivalent, whereas the value Host: is not a legal header key.
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
