Here is the routine I'm using. It looks in ram before the disk.
It is necessary to verify tf_YSize because if a font is found
in ram with a different size, OpenFont() will success.
Before using this you have to fill the TextAttr structure.

struct TextFont *LoadThisFont( struct TextAttr *TextAttr )
{
  struct TextFont *font;

    if ((font = (struct TextFont *) OpenFont( TextAttr ))
            && Font->tf_YSize != TextAttr->ta_YSize)
        {
        CloseFont( font );
        font = 0;
        }
    if (! font)
        {
        TextAttr->ta_Flags = FPF_DISKFONT;
        font = (struct TextFont *) OpenDiskFont( TextAttr );
        }
    return( font );
}

Hope this help.
