curl_easy_cleanup

Definition: include builtins\libcurl.e

curl_easy_cleanup(atom curl)
Description: End a libcurl easy session.

This procedure must be the last call for an easy session.
It is the opposite of the curl_easy_init function and must be called with the same handle that 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.
Do not 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 (if previously set for the handle using curl_easy_setopt).
For instance 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 has returned, is illegal.
curl_easy_cleanup kills the handle and all memory associated with it!

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.
[PL same deal as per IupRawStringPtr(); post-7.17.0 it makes internal copies, as per IupSetStrAttribute() vs. IupSetAttribute(), so you can safely discard strings immediately, long before calling curl_easy_cleanup.]
Example:
include builtins\libcurl.e

curl_global_init()
atom curl = curl_easy_init()
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com")
atom res = curl_easy_perform(curl)
curl_easy_cleanup(curl)
curl_global_cleanup()
