Funkce

int is_any_key_pressed() vraci 1 kdyz je stisknuta klavesa 
int is_key_pressed(int scancode) vraci 1 kdyz je stisknut Scancode.
void scan_keyboard() volat  pred pouzitim is_key_pressed atd.
int get_scancode();  vraci  Scancode nebo -1 pukud neni stisknuta klavesa.
int keymap_trans(int scancode) prevadi Scancode na ASCII.
int scancode_trans(int asc) prevadi ASCII na Scancode.
void set_switch_functions(void (*off)(void),void (*on)(void))nastaveni funkci, ktere prepinaji
  z textu do garfiky a zpet
Prikald:
...
void text()
{
vga_setmode(TEXT);
}

void graph()
{
vga_setmode(G320x200x256);
}
...
	allow_switch(1);
	set_switch_function(text,graph);
...
	allow_switch(0);
...

void allow_switch(int on) on=1 pro povoleni prepinani on=0 pro zakaz prepinani.
