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. Don't call this function if you intend to transfer
21       more files, re-using handles is a key to good performance with libcurl.
22
23       Occasionally you may get your  progress  callback  or  header  callback
24       called from within curl_easy_cleanup(3) (if previously set for the han‐
25       dle using curl_easy_setopt(3)). Like if libcurl decides  to  shut  down
26       the  connection  and  the  protocol  is  of a kind that requires a com‐
27       mand/response sequence before disconnect. Examples  of  such  protocols
28       are FTP, POP3 and IMAP.
29
30       Any  use of the handle after this function has been called and have re‐
31       turned, is illegal. curl_easy_cleanup(3) kills the handle and all  mem‐
32       ory associated with it!
33
34       Passing  in a NULL pointer in handle will make this function return im‐
35       mediately with no action.
36

OLD TIMES

38       For libcurl versions before 7.17,: after you've called  this  function,
39       you can safely remove all the strings you've previously told libcurl to
40       use, as it won't use them anymore now.
41

RETURN VALUE

43       None

EXAMPLE

46       CURL *curl = curl_easy_init();
47       if(curl) {
48         CURLcode res;
49         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
50         res = curl_easy_perform(curl);
51         curl_easy_cleanup(curl);
52       }
