Detailed Description

Functions used to retrieve user input via the touch screen or keypad.

Provides the GetInput method, a function which polls for input events (screen touches and key presses).

Function Documentation

◆ attribute()

struct __attribute__ ( (packed) )

Information about an input event returned from GetInput. See documentation for individual members for more information.

Code representing which event occurred. Events with a value for this field which do not correspond to a macro beginning with EVENT_ must be ignored.

The data associated with the event. Under no circumstances should the sub-structure for an event type other than the one communicated by eventType be accessed.

Corresponding members:

EVENT_KEY: key
EVENT_TOUCH: touch_single

The events EVENT_ACTBAR_RESIZE, EVENT_ACTBAR_SWAP, EVENT_ACTBAR_ROTATE, EVENT_ACTBAR_ESC, and EVENT_ACTBAR_SETTINGS do not report any data.

The direction the key traveled. One of KEY_PRESSED, KEY_HELD or KEY_RELEASED.

The key code for the key. See macros beginning with KEYCODE_.

The direction of the touch. One of TOUCH_DOWN, TOUCH_HOLD_DRAG, TOUCH_ACT_BAR, or TOUCH_UP.

The X position of the cursor, in screen pixels. May be negative or be greater than or equal to the width of the screen.

The Y position of the cursor, in screen pixels. May be negative or be greater than or equal to the height of the screen.

Variable Documentation

◆ GetInput

int(* GetInput) (struct Input_Event *event, uint32_t unknown1, uint32_t unknown2) __attribute__((access(write_only	(	struct Input_Event *	event,
		uint32_t	unknown1,
		uint32_t	unknown2
	)

extern

Polls for any input events.

The event structure should be zeroed before calling GetInput.

Parameters

[out]	event	The input event's data.
	unknown1	An unknown value. The value `0xFFFFFFFF` or `0` must be supplied meaning wait or do not wait for a event.
	unknown2	An unknown value. The value `0x10` must be supplied.

Returns: Always returns 0.

◆ Input_IsAnyKeyDown

bool(* Input_IsAnyKeyDown) () ( )

extern

Returns true if any key on the keyboard is currently down.

Returns: True if a key is pressed, false otherwise.
