Measure text according to font

Say I create a font like so.

Code:

---

        HFONT font = CreateFont(f_height,f_width,0,0,f_weight,f_italic,
                                f_underline,f_strike,f_charset,OUT_TT_PRECIS,
                                CLIP_DEFAULT_PRECIS,f_quality,
                                FF_DONTCARE|DEFAULT_PITCH,font_name.c_str());
        SelectObject(hdc, font);

---

Pretend like everything works and is defined. :)

Now, how do I figure out the unit length of a text string displayed with that font? Ive been looking for hours for a library function that dose that, and all I have found is Graphics.MeasureString from the .NET framework. But I am not using .NET.

GetTextExtentPoint32()

I knew there was a library function out there, but damned if I could find it. :)

Thanks alot man.

If you use

DrawText()

then first use DT_CALCRECT to get the size.
