curl_easy_cleanup - End a libcurl easy handle
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.
