NAME

       CURLINFO_LOCAL_IP - get local IP address of last connection

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LOCAL_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 local end of 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

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_LOCAL_IP, &ip) && ip) {
           printf("Local IP: %s\n", ip);
         }

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