+# NAME
+
+CURLINFO_LASTSOCKET - get the last socket used
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LASTSOCKET, long *socket);
+~~~
+
+# DESCRIPTION
+
+Deprecated since 7.45.0. Use CURLINFO_ACTIVESOCKET(3) 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 If the socket is no longer valid, -1 is returned.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(3) as usual and
+let libcurl close the socket and cleanup other resources associated with the
+handle. This is typically used in combination with
+CURLOPT_CONNECT_ONLY(3).
+
+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
+CURLINFO_ACTIVESOCKET(3) instead, if possible.
+
+# PROTOCOLS
+
+All
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    long sockfd; /* does not work on win64! */
+    curl_easy_setopt(curl, CURLOPT_URL, "https://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);
+
+    if(res != CURLE_OK) {
+      printf("Error: %s\n", curl_easy_strerror(res));
+      return 1;
+    }
+  }
+}

+
+# AVAILABILITY
+
+Added in 7.15.2
+
+# RETURN VALUE
+
+Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
