curl_easy_cleanup(3) libcurl Manual curl_easy_cleanup(3)
NAME
curl_easy_cleanup - End a libcurl easy handle
SYNOPSIS
#include <curl/curl.h>
void curl_easy_cleanup(CURL *handle);
DESCRIPTION
This function must be the last function to call for an easy session. It
is the opposite of the curl_easy_init(3) function and must be called
with the same handle as input that a curl_easy_init(3) call returned.
This might close all connections this handle has used and possibly has
kept open until now - unless it was attached to a multi handle while
doing the transfers. Do not call this function if you intend to trans-
fer more files, re-using handles is a key to good performance with
libcurl.
Occasionally you may get your progress callback or header callback
called from within curl_easy_cleanup(3) (if previously set for the han-
dle using curl_easy_setopt(3)). Like if libcurl decides to shut down
the connection and the protocol is of a kind that requires a com-
mand/response sequence before disconnect. Examples of such protocols
are FTP, POP3 and IMAP.
Any use of the handle after this function has been called and have re-
turned, is illegal. curl_easy_cleanup(3) kills the handle and all mem-
ory associated with it!
To close an easy handle that has been used with the multi interface,
make sure to call curl_multi_remove_handle(3) first to remove it from
the multi handle before it is closed.
Passing in a NULL pointer in handle will make this function return im-
mediately with no action.
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
