Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLINFO_EFFECTIVE_URL - get the last used URL
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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 gets freed when you call curl_easy_cleanup(3) on the corresponding
|
|
CURL handle.
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
|
|
res = curl_easy_perform(curl);
|
|
if(res == 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);
|
|
}
|
|
}
