CURLINFO_LASTSOCKET - get the last socket used #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LASTSOCKET, long *socket); 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 If the socket is no longer valid, -1 is returned.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() 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. All

CURL *curl = curl_easy_init();
if(curl) {
 long sockfd; /* doesn't work on win64! */
 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);

 if(res != CURLE_OK) {
 printf("Error: %s\\n", curl_easy_strerror(res));
 return 1;
 }
}

Added in 7.15.2 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. curl_easy_getinfo "(3), " curl_easy_setopt "(3), " CURLINFO_ACTIVESOCKET "(3), "
