CURLINFO_PRIMARY_IP(3)     Library Functions Manual     CURLINFO_PRIMARY_IP(3)


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

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

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