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. 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 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. 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. None
