CURLINFO_LOCAL_IP(3)                libcurl               CURLINFO_LOCAL_IP(3)


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
       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, "https://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);
       }
