C (WinAPI) - get size of internet file

I download files from the Internet using InternetOpenUrl and InternetReadFile. How do I get the size of a file prior to downloading? When downloading manually from the Internet, you can see total size just as the download process begins, but how do I get that size?

According to MSDN you should use HttpQueryInfo to get the size of a resource accessed with InternetOpenUrl. The corresponding query flag is called HTTP_QUERY_CONTENT_LENGTH.
