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 null-terminated 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
       is reused at next request so you need  to  copy  the  string  if  you  want  to  keep  the
       information.

       The ip pointer is NULL or points to private memory. You MUST NOT free - it gets freed when
       you call curl_easy_cleanup(3) on the corresponding CURL handle.

PROTOCOLS

       All network based ones

EXAMPLE

       int main(void)
       {
         char *ip;
         CURLcode res;
         CURL *curl = curl_easy_init();

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

         /* Perform the transfer */
         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);
       }
