nng_http_res_alloc_error(3http)

SYNOPSIS

#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

int nng_http_res_alloc_error(nng_http_res **resp, uint16_t status);

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

HTTP support not configured.
