CURLINFO_PRIMARY_IP(3)     curl_easy_getinfo options    CURLINFO_PRIMARY_IP(3)

NAME
       CURLINFO_PRIMARY_IP - get IP address of last connection

SYNOPSIS
       #include <curl/curl.h>

       CURLcode   curl_easy_getinfo(CURL  *handle,  CURLINFO_PRIMARY_IP,  char
       **ip);

DESCRIPTION
       Pass a pointer to a char pointer to receive the pointer to a  zero-ter-
       minated  string  holding  the  IP address of the most recent connection
       done with this curl handle. This  string  may  be  IPv6  when  that  is
       enabled.  Note that you get a pointer to a memory area that will be re-
       used at next request so you need to copy the string if you want to keep
       the information.

       The  ip pointer will be NULL or pointing to private memory you MUST NOT
       free - it gets freed when you call curl_easy_cleanup(3) on  the  corre-
       sponding CURL handle.

PROTOCOLS
       All network based ones

EXAMPLE
       {
         char *ip;

         curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

         /* Perform the request, res will get the return code */
         res = curl_easy_perform(curl);
         /* Check for errors */
         if((res == CURLE_OK) &&
            !curl_easy_getinfo(curl, CURLINFO_PRIMARY_IP, &ip) && ip) {
           printf("IP: %s\n", ip);
         }

         /* always cleanup */
         curl_easy_cleanup(curl);
       }
