23 .TH CURLINFO_ACTIVESOCKET 3 "May 06, 2017" "libcurl 7.59.0" "curl_easy_getinfo options"
26 CURLINFO_ACTIVESOCKET \- get the active socket
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_ACTIVESOCKET,
31 curl_socket_t *socket);
33 Pass a pointer to a curl_socket_t to receive the active socket used by this
34 curl session. If the socket is no longer valid, \fICURL_SOCKET_BAD\fP is
35 returned. When you finish working with the socket, you must call
36 \fIcurl_easy_cleanup(3)\fP as usual on the easy handle and let libcurl close
37 the socket and cleanup other resources associated with the handle. This is
38 typically used in combination with \fICURLOPT_CONNECT_ONLY(3)\fP.
40 This option was added as a replacement for \fICURLINFO_LASTSOCKET(3)\fP since
41 that one isn't working on all platforms.
46 CURL *curl = curl_easy_init();
49 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
51 /* Do not do the transfer - only connect to host */
52 curl_easy_setopt(curl, CURLOPT_CONNECT_ONLY, 1L);
53 res = curl_easy_perform(curl);
55 /* Extract the socket from the curl handle */
56 res = curl_easy_getinfo(curl, CURLINFO_ACTIVESOCKET, &sockfd);
59 printf("Error: %s\\n", curl_easy_strerror(res));
67 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
