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-ter-
       minated string holding the IP address of	 the  most  recent  connection
       done  with  this	 curl handle. This string may be IPv6 when that	is en-
       abled. 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 in-
       formation.

       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);
       }

AVAILABILITY
       Added in	curl 7.19.0

RETURN VALUE
       curl_easy_getinfo(3) returns a CURLcode indicating success or error.

       CURLE_OK	(0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
