+.TH CURLINFO_ACTIVESOCKET 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
+.SH NAME
+CURLINFO_ACTIVESOCKET \- get the active socket
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_ACTIVESOCKET,
+                           curl_socket_t *socket);
+.SH DESCRIPTION
+Pass a pointer to a curl_socket_t to receive the active socket used by this
+curl session. If the socket is no longer valid, \fICURL_SOCKET_BAD\fP is
+returned. When you finish working with the socket, you must call
+\fIcurl_easy_cleanup(3)\fP as usual on the easy handle 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.
+
+This option was added as a replacement for \fICURLINFO_LASTSOCKET(3)\fP since
+that one isn't working on all platforms.
+.SH PROTOCOLS
+All
+.SH EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  curl_socket_t sockfd;
+  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_ACTIVESOCKET, &sockfd);
+
+  if(res != CURLE_OK) {
+    printf("Error: %s\\n", curl_easy_strerror(res));
+    return 1;
+  }
+}
+.fi
+.SH AVAILABILITY
+Added in 7.45.0
+.SH RETURN VALUE
+Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
