How to use libcurl to get the final URL of a site after a redirection ?

I am a beginner at libcurl.

I have installed curl 7.72.0-DEV (x86_64-pc-win32) libcurl/7.72.0-DEV
Schannel WinIDN. I work with MinGW C/C++ on Windows 7 and Windows 10.

What I wish to do.

I would like to write a function to obtain the final URL from a site which
redirects to another site using libcurl functions. I need some guidance on
this.

Example.

The site "http://site.com" redirects to
"https://www.salesforce.com/products/platform/overview".

So, I would like my function to return the final URL as an output when given
the initial URL as an input. I do not need the whole body of the redirected
page. Only the new URL.

What I have done so far.

Gone through the libcurl documentation and tried some of the examples given.

For instance, getredirect.c
(https://curl.haxx.se/libcurl/c/getredirect.html)

However, I didn't get the desired result.

My apologies if my question is trivial or has already been answered. The
curl-library seems huge !

Could someone help ?
