+# NAME
+
+curl_easy_cleanup - free an easy handle
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+void curl_easy_cleanup(CURL *handle);
+~~~
+
+# DESCRIPTION
+
+This function is the opposite of curl_easy_init(3). It closes down and frees
+all resources previously associated with this easy handle.
+
+This call closes all connections this handle has used and possibly has kept
+open until now unless the easy handle was attached to a multi handle while
+doing the transfers. Do not call this function if you intend to transfer more
+files, reusing 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 easy **handle** after this function has been called and have
+returned, is illegal.
+
+To close an easy handle that has been used with the multi interface, make sure
+to first call curl_multi_remove_handle(3) to remove it from the multi handle
+before it is closed.
+
+Passing in a NULL pointer in *handle* makes this function return immediately
+with no action.
