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. Don't 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 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! Passing in a NULL pointer in handle will make this function return im- mediately with no action. OLD TIMES For libcurl versions before 7.17,: after you've called this function, you can safely remove all the strings you've previously told libcurl to use, as it won't use them anymore now. RETURN VALUE None EXAMPLE CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } SEE ALSO curl_easy_init(3), curl_easy_duphandle(3), curl_easy_reset(3), curl_multi_cleanup(3), curl_multi_remove_handle(3) libcurl 7.72.0 August 09, 2018 curl_easy_cleanup(3)
