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 \fBip\fP pointer will be NULL or pointing to private memory you MUST NOT +free - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the +corresponding CURL handle. +.SH PROTOCOLS +All network based ones +.SH EXAMPLE +.nf +{ + 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\\n", ip); + } + + /* always cleanup */ + curl_easy_cleanup(curl); +} +.fi +.SH AVAILABILITY +Added in 7.19.0 +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR curl_easy_getinfo "(3), " curl_easy_setopt "(3), " +.BR CURLINFO_PRIMARY_PORT "(3), " CURLINFO_LOCAL_IP "(3), " |
