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

◆ GetInput()

int GetInput ( struct InputEvent *  event,
uint32_t  unknown1,
uint32_t  unknown2 
)

Polls for any input events.

The event structure should be zeroed before calling GetInput.

Parameters
[out]eventThe input event's data.
unknown1An unknown value. The value 0xFFFFFFFF must be supplied.
unknown2An unknown value. The value 0x10 must be supplied.
Returns
Always returns 0.

◆ Input_GetKeyState()

bool Input_GetKeyState ( InputScancode *  scancode)

Returns true if the specified key is currently down.

Parameters
[in]scanCodeThe scancode of the key to check.
Returns
True if the key is down, false otherwise.

◆ Input_IsAnyKeyDown()

bool Input_IsAnyKeyDown ( )

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

Returns
True if a key is pressed, false otherwise.
