42  * @con_init:   initialize the console on @vc. @init is true for the very first
43  *		call on this @vc.
44  * @con_deinit: deinitialize the console from @vc.
45  * @con_clear:  erase @count characters at [@x, @y] on @vc. @count >= 1.
46  * @con_putc:   emit one character with attributes @ca to [@x, @y] on @vc.
48  * @con_putcs:  emit @count characters with attributes @s to [@x, @y] on @vc.
58  * @con_font_set: set console @vc font to @font with height @vpitch. @flags can
60  * @con_font_get: fetch the current font on @vc of height @vpitch into @font.
62  * @con_font_default: set default font on @vc. @name can be %NULL or font name
64  * @con_resize:	resize the @vc console to @width x @height. @from_user is true
66  * @con_set_palette: sets the palette of the console @vc to @table (optional)
69  * @con_set_origin: set origin (see &vc_data::vc_origin) of the @vc. If not
71  *		@vc->vc_screenbuf. (optional)
72  * @con_save_screen: save screen content into @vc->vc_screenbuf. Called e.g.
77  * @con_invert_region: invert a region of length @count on @vc starting at @p.
