NAME
nng_http_res_alloc_error - allocate HTTP error response
SYNOPSIS
DESCRIPTION
The nng_http_res_alloc_error() function allocates a new HTTP response structure
and stores a pointer to it in resp.
The response will be initialized
with the status code status, a corresponding reason phrase, and
a simple HTML page containing the same information will be generated and
attached to the response.
(Relevant HTTP headers will be set as well, such as Content-Type
and Content-Length.)
The HTTP protocol version is also set to "HTTP/1.1".
| This is the simplest way to generate an error response. |
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
