.TH CURLINFO_LASTSOCKET 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
|
|
.SH NAME
|
|
CURLINFO_LASTSOCKET \- get the last socket used
|
|
.SH SYNOPSIS
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LASTSOCKET, long *socket);
|
|
.SH DESCRIPTION
|
|
Deprecated since 7.45.0. Use \fICURLINFO_ACTIVESOCKET(3)\fP instead.
|
|
|
|
Pass a pointer to a long to receive the last socket used by this curl
|
|
session. If the socket is no longer valid, -1 is returned. When you finish
|
|
working with the socket, you must call curl_easy_cleanup() as usual and let
|
|
libcurl close the socket and cleanup other resources associated with the
|
|
handle. This is typically used in combination with
|
|
\fICURLOPT_CONNECT_ONLY(3)\fP.
|
|
|
|
NOTE: this API is deprecated since it is not working on win64 where the SOCKET
|
|
type is 64 bits large while its 'long' is 32 bits. Use the
|
|
\fICURLINFO_ACTIVESOCKET(3)\fP instead, if possible.

|

curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
|
|
|
|
/* Do not do the transfer - only connect to host */
|
|
curl_easy_setopt(curl, CURLOPT_CONNECT_ONLY, 1L);
|
|
res = curl_easy_perform(curl);
|
|
|
|
/* Extract the socket from the curl handle */
|
|
res = curl_easy_getinfo(curl, CURLINFO_LASTSOCKET, &sockfd);
