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 null-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 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

       This functionality affects all supported protocols

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

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