curl_easy_cleanup - End a libcurl easy handle


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


This function must be the last function to call for an easy session. It is the opposite of the curl_easy_init function and must be called with the same handle as input that a curl_easy_init 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 transfer 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 (if previously set for the handle using curl_easy_setopt). Like if libcurl decides to shut down the connection and the protocol is of a kind that requires a command/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 returned, is illegal. curl_easy_cleanup kills the handle and all memory associated with it!

To close an easy handle that has been used with the multi interface, make sure to call curl_multi_remove_handle first to remove it from the multi handle before it is closed.

Passing in a NULL pointer in handle will make this function return immediately with no action.


CURL *curl = curl_easy_init();
if(curl) {
  CURLcode res;
  curl_easy_setopt(curl, CURLOPT_URL, "");
  res = curl_easy_perform(curl);
