It closes down and frees 30all resources previously associated with this easy handle. 31 32This call closes all connections this handle has used and possibly has kept 33open until now unless the easy handle was attached to a multi handle while 34doing the transfers. Do not call this function if you intend to transfer more 35files, reusing handles is a key to good performance with libcurl. 36 37Occasionally you may get your progress callback or header callback called from 38within curl_easy_cleanup(3) (if previously set for the handle using 39curl_easy_setopt(3)). Like if libcurl decides to shut down the connection and 40the protocol is of a kind that requires a command/response sequence before 41disconnect. Examples of such protocols are FTP, POP3 and IMAP. 42 43Any use of the easy **handle** after this function has been called and have 44returned, is illegal. 45 46To close an easy handle that has been used with the multi interface, make sure 47to first call curl_multi_remove_handle(3) to remove it from the multi handle 48before it is closed. 49 50Passing in a NULL pointer in *handle* makes this function return immediately 51with no action. 52 53# EXAMPLE 54 55~~~c 56int main(void) 57{ 58 CURL *curl = curl_easy_init(); 59 if(curl) { 60 CURLcode res; 61 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); 62 res = curl_easy_perform(curl); 63 if(res) 64 printf("error: %s\n", curl_easy_strerror(res)); 65 curl_easy_cleanup(curl); 66 } 67} 68~~~ 69 70# AVAILABILITY 71 72Added in 7.1 73 74# RETURN VALUE 75 76None 77
