23 .TH CURLINFO_PRIMARY_IP 3 "March 22, 2017" "libcurl 7.59.0" "curl_easy_getinfo options"
26 CURLINFO_PRIMARY_IP \- get IP address of last connection
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_IP, char **ip);
32 Pass a pointer to a char pointer to receive the pointer to a zero-terminated
33 string holding the IP address of the most recent connection done with this
34 \fBcurl\fP handle. This string may be IPv6 when that is enabled. Note that you
35 get a pointer to a memory area that will be re-used at next request so you
36 need to copy the string if you want to keep the information.
38 The \fBip\fP pointer will be NULL or pointing to private memory you MUST NOT
39 free - it gets freed when you call \fIcurl_easy_cleanup(3)\fP on the
40 corresponding CURL handle.
42 All network based ones
48 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
50 /* Perform the request, res will get the return code */
51 res = curl_easy_perform(curl);
52 /* Check for errors */
53 if((res == CURLE_OK) &&
54 !curl_easy_getinfo(curl, CURLINFO_PRIMARY_IP, &ip) && ip) {
55 printf("IP: %s\\n", ip);
59 curl_easy_cleanup(curl);
65 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
