CURLINFO_LOCAL_IP(3) curl_easy_getinfo options CURLINFO_LOCAL_IP(3) NAME CURLINFO_LOCAL_IP - get local IP address of last connection SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_LOCAL_IP, char **ip); DESCRIPTION Pass a pointer to a char pointer to receive the pointer to a null-ter- minated string holding the IP address of the local end of most recent connection done with this curl 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 ip pointer will be NULL or pointing to private memory you MUST NOT free - it gets freed when you call curl_easy_cleanup(3) on the corre- sponding CURL handle. PROTOCOLS All EXAMPLE { char *ip; curl_easy_setopt(curl, CURLOPT_URL, "https://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_LOCAL_IP, &ip) && ip) { printf("Local IP: %s\n", ip); } /* always cleanup */ curl_easy_cleanup(curl); } AVAILABILITY Added in 7.21.0 RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
