NAME

nng_http_req_alloc - allocate HTTP request structure

SYNOPSIS

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

int nng_http_req_alloc(nng_http_req **reqp, const nng_url *url);

DESCRIPTION

The nng_http_req_alloc() function allocates a new HTTP request structure and stores a pointer to it in reqp. The request will be initialized to perform an HTTP/1.1 GET operation using the URL specified in url.

It is possible to specify NULL for the URL. In this case the URI for the request must be specified by a subsequent call to nng_http_req_set_uri().

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.
