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  zero-ter-
       minated  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  corre-
       sponding CURL handle.
