CURLINFO_PRIMARY_IP(3) libcurl CURLINFO_PRIMARY_IP(3)
NAME
CURLINFO_PRIMARY_IP - get IP address of last connection
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIMARY_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 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 is reused at
next request so you need to copy the string if you want to keep the
information.
The ip pointer is NULL or points to private memory. You MUST NOT free -
it gets freed when you call curl_easy_cleanup(3) on the corresponding
CURL handle.
PROTOCOLS
All network based ones
EXAMPLE
{
char *ip;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Perform the transfer */
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);
}
AVAILABILITY
Added in 7.19.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
if not.
