CURLINFO_PRIMARY_IP(3)					     curl_easy_getinfo options					    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 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 cor-
       responding 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
", ip);
	 }

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

AVAILABILITY
       Added in 7.19.0
