D3D I had a little trouble making it work from the readme but it's working great now.

Here's the example which loads a font called Pristina.ttf

Code:
var dll_handle;
string Pristina = <pristina.ttf>;
dllfunction InstallFont(Pristina);

function main()
{

dll_handle=dll_open("FontInstall.dll");
InstallFont(Pristina);
...
