/*
|
|
* wsfont_find() can be called with any of the parameters as 0, meaning we
|
|
* don't care about that aspect of the font. It returns a cookie which
|
|
* we can use with the other functions. When more flexibility is required,
|
|
* wsfont_enum() should be used. The last two parameters to wsfont_lock()
|
|
* are the bit order and byte order required (WSFONT_L2R or WSFONT_R2L).
|
|
*
|
|
* Example:
|
|
*
|
|
* struct wsdisplay_font *font;
|
|
* int cookie;
|
|
*
|
|
* if ((cookie = wsfont_find(NULL, 8, 16, 0, 0)) <= 0)
|
|
* panic("unable to get 8x16 font");
|
|
*
|
|
* if (wsfont_lock(cookie, &font, WSFONT_L2R, WSFONT_R2L) <= 0)
|
|
* panic("unable to lock font");
|
|
*
|
|
* ... do stuff ...
|
|
*
|
|
* wsfont_unlock(cookie);
