CURLINFO_EFFECTIVE_URL(3) Library Functions Manual CURLINFO_EFFECTIVE_URL(3)
NAME
CURLINFO_EFFECTIVE_URL - last used URL
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_EFFECTIVE_URL, char **urlp);
DESCRIPTION
Pass in a pointer to a char pointer and get the last used effective URL.
In cases when you have asked libcurl to follow redirects, it may not be
the same value you set with CURLOPT_URL(3).
The urlp pointer is NULL or points to private memory. You must not free
it. It memory gets freed automatically when you call curl_easy_cleanup(3)
on the corresponding curl handle.
The returned string has limited life-time. It might get destroyed at the
next libcurl function call involving this same handle.
PROTOCOLS
This functionality affects http only
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode result;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
result = curl_easy_perform(curl);
if(result == CURLE_OK) {
char *url = NULL;
curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_URL, &url);
if(url)
printf("Redirect to: %s\n", url);
}
curl_easy_cleanup(curl);
}
}
AVAILABILITY
