44: * wsfont_find() can be called with any of the parameters as 0, meaning we
45: * don't care about that aspect of the font. It returns a cookie which
46: * we can use with the other functions. When more flexibility is required,
47: * wsfont_enum() should be used. The last two parameters to wsfont_lock()
48: * are the bit order and byte order required (WSDISPLAY_FONTORDER_L2R or
49: * WSDISPLAY_FONTORDER_R2L).
50: *
51: * Example:
52: *
53: * struct wsdisplay_font *font;
54: * int cookie;
55: *
56: * if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) <= 0)
57: * panic("unable to get 8x16 font");
58: *
59: * if (wsfont_lock(cookie, &font, WSDISPLAY_FONTORDER_L2R,
60: * WSDISPLAY_FONTORDER_R2L) <= 0)
61: * panic("unable to lock font");
62: *
63: * ... do stuff ...
64: *
65: * wsfont_unlock(cookie);
