Thread: Shell functions on Win XP

Hi.
I've got a book that teaches how to program for Windows 2000 but currently I'm using Windows XP to learn programming. In the "PIDL functions" section of the book under "Shell functions", it's got some code examples that uses Shell functions like SHGetMalloc(), SHGetFolderLocation(). I get errors when compiling thoes codes saying that it doesn't recognize above functions. Is this because I'm using XP so I have to change the code to suit XP?
Thanks.
