# NAME
|
|
|
|
|
|
|
|
curl_easy_cleanup - End a libcurl 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.
