CURLINFO_LASTSOCKET (3)

Name

CURLINFO_LASTSOCKET - get the last socket used

Synopsis

#include <curl/curl.h>

CURLcode   curl_easy_getinfo(CURL  *handle,  CURLINFO_LASTSOCKET,  long
*socket);

Description

CURLINFO_LASTSOCKET(3)     curl_easy_getinfo options    CURLINFO_LASTSOCKET(3)



NAME
       CURLINFO_LASTSOCKET - get the last socket used

SYNOPSIS
       #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  If  the  socket  is no longer valid, -1 is returned.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()  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
       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;
         }
       }

AVAILABILITY
       Added in 7.15.2

RETURN VALUE
       Returns  CURLE_OK  if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
