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(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 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(3) (if previously set for the handle using curl_easy_setopt(3)). 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(3) kills the handle and all memory associated with it!

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, "https://example.com");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
