.SH NAME
curl_easy_cleanup - End a libcurl easy handle
.SH SYNOPSIS
.nf
#include <curl/curl.h>
void curl_easy_cleanup(CURL *handle);
.fi
.SH DESCRIPTION
This function is the opposite of \fIcurl_easy_init(3)\fP. 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 \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 easy \fBhandle\fP 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 \fIcurl_multi_remove_handle(3)\fP to remove it from the multi
handle before it is closed.
Passing in a NULL pointer in \fIhandle\fP makes this function return
immediately with no action.
.SH EXAMPLE
.nf
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
res = curl_easy_perform(curl);
if(res)
printf("error: %s\\n", curl_easy_strerror(res));
curl_easy_cleanup(curl);
}
}
.fi
