[Dev-C++] COLOREF, libraries

[Brian D. <Bri...@ms...>]

I need to use COLOREF to paint my windows background but I don't think =
I'm linking the right library.   Two questions:

Which library or header should I include/link to for access to COLOREF?  =
I'm already linking to lgdi32.

How do I know what each library contains when I'm looking for a =
function? =20

Thanks, Brian
