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-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 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 corresponding 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);
       }

AVAILABILITY
