| .TH CURLINFO_PRIMARY_IP 3 "12 Sep 2015" "libcurl 7.44.0" "curl_easy_getinfo options" |
| .SH NAME |
| CURLINFO_PRIMARY_IP \- get IP address of last connection |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_IP, char **ip); |
| .SH DESCRIPTION |
| Pass a pointer to a char pointer to receive the pointer to a zero-terminated |
| string holding the IP address of the most recent connection done with this |
| \fBcurl\fP 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 \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. |
