NAME

6       curl_easy_cleanup - End a libcurl easy handle
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       void curl_easy_cleanup(CURL *handle);
12

DESCRIPTION

14       This function must be the last function to call for an easy session. It
15       is the opposite of the curl_easy_init(3) function and  must  be  called
16       with the same handle as input that a curl_easy_init(3) call returned.
17
18       This  might close all connections this handle has used and possibly has
19       kept open until now - unless it was attached to a  multi  handle  while
20       doing  the transfers. Do not call this function if you intend to trans‐
21       fer more files, re-using handles is a  key  to  good  performance  with
22       libcurl.
23
24       Occasionally  you  may  get  your  progress callback or header callback
25       called from within curl_easy_cleanup(3) (if previously set for the han‐
26       dle  using  curl_easy_setopt(3)).  Like if libcurl decides to shut down
27       the connection and the protocol is of  a  kind  that  requires  a  com‐
28       mand/response  sequence  before  disconnect. Examples of such protocols
29       are FTP, POP3 and IMAP.
30
31       Any use of the handle after this function has been called and have  re‐
32       turned,  is illegal. curl_easy_cleanup(3) kills the handle and all mem‐
33       ory associated with it!
34
35       To close an easy handle that has been used with  the  multi  interface,
36       make  sure  to call curl_multi_remove_handle(3) first to remove it from
37       the multi handle before it is closed.
38
39       Passing in a NULL pointer in handle will make this function return  im‐
40       mediately with no action.

EXAMPLE

43       CURL *curl = curl_easy_init();
44       if(curl) {
45         CURLcode res;
46         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
47         res = curl_easy_perform(curl);
48         curl_easy_cleanup(curl);
49       }
