.TH curl_easy_cleanup 3 "22 aug 2007" "libcurl 7.17.0" "libcurl Manual"
.SH NAME
curl_easy_cleanup - End a libcurl easy handle
.SH SYNOPSIS
.B #include <curl/curl.h>

.BI "void curl_easy_cleanup(CURL *" handle ");"
.SH DESCRIPTION
This function must be the last function to call for an easy session. It is the
opposite of the \fIcurl_easy_init(3)\fP function and must be called with the
same \fIhandle\fP as input that a \fIcurl_easy_init(3)\fP 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 \fIcurl_easy_cleanup(3)\fP (if previously set for the handle using
\fIcurl_easy_setopt(3)\fP). 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 \fBhandle\fP after this function has been called and have
returned, is illegal. \fIcurl_easy_cleanup(3)\fP 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.
.SH RETURN VALUE
None
.SH EXAMPLE
.nf
CURL *curl = curl_easy_init();
if(curl) {
  CURLcode res;
  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

  curl_easy_cleanup(curl);
}
