How to scrool -- actually how to find info in Petzold &/or WIN32API.HLP

I am using DrawText to display arbitrary length text in a specified
font size in a fixed size window. Specifying the DT_WORDBREAK flag
nicely handles breaking displayed lines between words.

I need some way to how many characters are displayed on the first line
so that I can scroll one display line at a time. It would appear that
there should be an analog of calling DrawText with the DT_CALCRECT
flag.

I can't find it. Probably because I'm not looking in quite the right
place.
