        !            27: .SH SYNOPSIS
        !            28: #include <curl/curl.h>
        !            29: 
        !            30: CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LOCAL_IP, char **ip);
        !            31: .SH DESCRIPTION
        !            32: Pass a pointer to a char pointer to receive the pointer to a zero-terminated
        !            33: string holding the IP address of the local end of most recent connection done
        !            34: with this \fBcurl\fP handle. This string may be IPv6 when that is
        !            35: enabled. Note that you get a pointer to a memory area that will be re-used at
        !            36: next request so you need to copy the string if you want to keep the
        !            37: information.
        !            38: 
        !            39: The \fBip\fP pointer will be NULL or pointing to private memory you MUST NOT
        !            40: free - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
        !            41: corresponding CURL handle.
