XINPUT_KEYSTROKE structure

Specifies keystroke data returned by XInputGetKeystroke.

Syntax

typedef struct _XINPUT_KEYSTROKE {
  WORD  VirtualKey;
  WCHAR Unicode;
  WORD  Flags;
  BYTE  UserIndex;
  BYTE  HidCode;
} XINPUT_KEYSTROKE, *PXINPUT_KEYSTROKE;

Members

VirtualKey

Virtual-key code of the key, button, or stick movement. See XInput.h for a list of valid virtual-key (VK_xxx) codes. Also, see Remarks.

Unicode

This member is unused and the value is zero.

Flags

Flags that indicate the keyboard state at the time of the input event. This member can be any combination of the following flags:

Value Description
XINPUT_KEYSTROKE_KEYDOWN The key was pressed. 
XINPUT_KEYSTROKE_KEYUP The key was released. 
XINPUT_KEYSTROKE_REPEAT A repeat of a held key. 

UserIndex

Index of the signed-in gamer associated with the device. Can be a value in the range 0–3.

HidCode

HID code corresponding to the input. If there is no corresponding HID code, this value is zero.

Remarks

Future devices may return HID codes and virtual key values that are not supported on current devices, and are currently undefined. Applications should ignore these unexpected values.

A virtual-key code is a byte value that represents a particular physical key on the keyboard, not the character or characters (possibly none) that the key can be mapped to based on keyboard state. The keyboard state at the time a virtual key is pressed modifies the character reported. For example, VK_4 might represent a "4" or a "$", depending on the state of the SHIFT key.

A reported keyboard event includes the virtual key that caused the event, whether the key was pressed or released (or is repeating), and the state of the keyboard at the time of the event. The keyboard state includes information about whether any CTRL, ALT, or SHIFT keys are down.

If the keyboard event represents an Unicode character (for example, pressing the "A" key), the Unicode member will contain that character. Otherwise, Unicode will contain the value zero.

The valid virtual-key (VK_xxx) codes are defined in XInput.h. In addition to codes that indicate key presses, the following codes indicate controller input.

VK_PAD_A A button 
VK_PAD_B B button
