🍪 CURLINFO_COOKIELIST 💅

okay so this page is from the Library Functions Manual, and it's literally about cookies, which is iconic. 🍪✨ no cap, this is the one that gives you all the cookies curl knows about.

✨ NAME ✨

CURLINFO_COOKIELIST - all known cookies 🍪💖

🎀 SYNOPSIS 🎀

okay bestie, here's the exact signature, fr fr:

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_COOKIELIST,
                                  struct curl_slist **cookies);

💖 DESCRIPTION 💖

okay so here's the tea: you pass a pointer to a struct curl_slist * to receive a linked-list of all cookies curl knows (expired ones, too) — no cap. 🍪

⚠️ bestie, do not forget to call curl_slist_free_all(3) on the list after it has been used, or you'll be leaking memory and that's not the vibe. 💅

if there are no cookies (cookies for the handle have not been enabled or simply none have been received) the struct curl_slist * is made a NULL pointer. so yeah, it's giving nothing. 🙈

since 7.43.0 cookies that were imported in the Set-Cookie format without a domain name are not exported by this option. iykyk. 🫶

🌈 PROTOCOLS 🌈

This functionality affects http only 🌸

✨ EXAMPLE ✨

okay so here's a whole example, it's literally giving main character energy 👑:

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode result;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

           /* enable the cookie engine */
           curl_easy_setopt(curl, CURLOPT_COOKIEFILE, "");

           result = curl_easy_perform(curl);

           if(!result) {
             /* extract all known cookies */
             struct curl_slist *cookies = NULL;
             result = curl_easy_getinfo(curl, CURLINFO_COOKIELIST, &cookies);
             if(!result && cookies) {
               /* a linked list of cookies in cookie file format */
               struct curl_slist *each = cookies;
               while(each) {
                 printf("%s\n", each->data);
                 each = each->next;
               }
               /* we must free these cookies when we are done */
               curl_slist_free_all(cookies);
             }
           }
           curl_easy_cleanup(curl);
         }
       }

🦋 AVAILABILITY 🦋

Added in curl 7.14.1 ✨

💜 RETURN VALUE 💜

curl_easy_getinfo(3) returns a CURLcode indicating success or error. 😌

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3). so like, if it's not zero, something went wrong, bestie. 💀
