wlr_keyboard_from_input_device() 

struct wlr_keyboard *wlr_keyboard_from_input_device(​struct wlr_input_device *input_device);

Get a struct wlr_keyboard from a struct wlr_input_device.

Asserts that the input device is a keyboard.

wlr_keyboard_get_modifiers() 

uint32_t wlr_keyboard_get_modifiers(​struct wlr_keyboard *keyboard);

Get the set of currently depressed or latched modifiers.

A bitmask of enum wlr_keyboard_modifier is returned.

struct wlr_keyboard_key_event 

struct wlr_keyboard_key_event {
	uint32_t time_msec;
	uint32_t keycode;
	bool update_state; // if backend doesn't update modifiers on its own
	enum wl_keyboard_key_state state;
};

wlr_keyboard_keymaps_match() 

bool wlr_keyboard_keymaps_match(​struct xkb_keymap *km1, struct xkb_keymap *km2);

};

wlr_keyboard_led_update() 

void wlr_keyboard_led_update(​struct wlr_keyboard *keyboard, uint32_t leds);

Update the LEDs on the device, if any.

leds is a bitmask of enum wlr_keyboard_led.

If the device doesn't have the provided LEDs, this function is a no-op.

wlr_keyboard_set_keymap() 

bool wlr_keyboard_set_keymap(​struct wlr_keyboard *kb, struct xkb_keymap *keymap);

wlr_keyboard_set_repeat_info() 

void wlr_keyboard_set_repeat_info(​struct wlr_keyboard *kb, int32_t rate_hz, int32_t delay_ms);

Set the keyboard repeat info.

rate is in key repeats/second and delay is in milliseconds.
