11 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_IP, char
12 **ip);
13
15 Pass a pointer to a char pointer to receive the pointer to a zero-ter‐
16 minated string holding the IP address of the most recent connection
17 done with this curl handle. This string may be IPv6 when that is
18 enabled. Note that you get a pointer to a memory area that will be re-
19 used at next request so you need to copy the string if you want to keep
20 the information.
21
22 The ip pointer will be NULL or pointing to private memory you MUST NOT
23 free - it gets freed when you call curl_easy_cleanup(3) on the corre‐
24 sponding CURL handle.
