EFI_GUID | gEfiSimpleTextInputExProtocolGuid |
Simple Text Input Ex protocol from the UEFI 2.0 specification.
This protocol defines an extension to the EFI_SIMPLE_TEXT_INPUT_PROTOCOL which exposes much more state and modifier information from the input device, also allows one to register a notification for a particular keystroke.

typedef EFI_STATUS(EFIAPI * EFI_INPUT_READ_KEY_EX) (IN EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL *This, OUT EFI_KEY_DATA *KeyData) |
The function reads the next keystroke from the input device. If there is no pending keystroke the function returns EFI_NOT_READY. If there is a pending keystroke, then KeyData.Key.ScanCode is the EFI scan code defined in Error! Reference source not found. The KeyData.Key.UnicodeChar is the actual printable character or is zero if the key does not represent a printable character (control key, function key, etc.). The KeyData.KeyState is shift state for the character reflected in KeyData.Key.UnicodeChar or KeyData.Key.ScanCode . When interpreting the data from this function, it should be noted that if a class of printable characters that are normally adjusted by shift modifiers (e.g. Shift Key + "f" key) would be presented solely as a KeyData.Key.UnicodeChar without the associated shift state. So in the previous example of a Shift Key + "f" key being pressed, the only pertinent data returned would be KeyData.Key.UnicodeChar with the value of "F". This of course would not typically be the case for non-printable characters such as the pressing of the Right Shift Key + F10 key since the corresponding returned data would be reflected both in the KeyData.KeyState.KeyShiftState and KeyData.Key.ScanCode values. UEFI drivers which implement the EFI_SIMPLE_TEXT_INPUT_EX protocol are required to return KeyData.Key and KeyData.KeyState values. These drivers must always return the most current state of KeyData.KeyState.KeyShiftState and KeyData.KeyState.KeyToggleState. It should also be noted that certain input devices may not be able to produce shift or toggle state information, and in those cases the high order bit in the respective Toggle and Shift state fields should not be active.
This | A pointer to the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL instance. |
KeyData | A pointer to a buffer that is filled in with the keystroke state data for the key that was pressed. |
EFI_SUCCESS | The keystroke information was returned. |
EFI_NOT_READY | There was no keystroke data available. EFI_DEVICE_ERROR The keystroke information was not returned due to hardware errors. |
Definition at line 204 of file SimpleTextInEx.h.
typedef EFI_STATUS(EFIAPI * EFI_INPUT_RESET_EX) (IN EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL *This, IN BOOLEAN ExtendedVerification) |
The Reset() function resets the input device hardware. As part of initialization process, the firmware/device will make a quick but reasonable attempt to verify that the device is functioning. If the ExtendedVerification flag is TRUE the firmware may take an extended amount of time to verify the device is operating on reset. Otherwise the reset operation is to occur as quickly as possible. The hardware verification process is not defined by this specification and is left up to the platform firmware or driver to implement.
This | A pointer to the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL instance. |
ExtendedVerification | Indicates that the driver may perform a more exhaustive verification operation of the device during reset. |
EFI_SUCCESS | The device was reset. |
EFI_DEVICE_ERROR | The device is not functioning correctly and could not be reset. |
Definition at line 56 of file SimpleTextInEx.h.
typedef EFI_STATUS(EFIAPI * EFI_KEY_NOTIFY_FUNCTION) (IN EFI_KEY_DATA *KeyData) |
The function will be called when the key sequence is typed specified by KeyData.
Definition at line 241 of file SimpleTextInEx.h.
typedef struct _EFI_KEY_STATE EFI_KEY_STATE |
typedef UINT8 EFI_KEY_TOGGLE_STATE |
EFI_KEY_TOGGLE_STATE. The toggle states are defined. They are: EFI_TOGGLE_STATE_VALID, EFI_SCROLL_LOCK_ACTIVE EFI_NUM_LOCK_ACTIVE, EFI_CAPS_LOCK_ACTIVE
Definition at line 68 of file SimpleTextInEx.h.
typedef EFI_STATUS(EFIAPI * EFI_REGISTER_KEYSTROKE_NOTIFY) (IN EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL *This, IN EFI_KEY_DATA *KeyData, IN EFI_KEY_NOTIFY_FUNCTION KeyNotificationFunction, OUT EFI_HANDLE *NotifyHandle) |
The RegisterKeystrokeNotify() function registers a function which will be called when a specified keystroke will occur.
This | A pointer to the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL instance. |
KeyData | A pointer to a buffer that is filled in with the keystroke information for the key that was pressed. |
KeyNotificationFunction | Points to the function to be called when the key sequence is typed specified by KeyData. |
NotifyHandle | Points to the unique handle assigned to the registered notification. |
EFI_SUCCESS | The device state was set appropriately. |
EFI_OUT_OF_RESOURCES | Unable to allocate necessary data structures. |
Definition at line 272 of file SimpleTextInEx.h.
typedef EFI_STATUS(EFIAPI * EFI_SET_STATE) (IN EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL *This, IN EFI_KEY_TOGGLE_STATE *KeyToggleState) |
The SetState() function allows the input device hardware to have state settings adjusted.
This | A pointer to the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL instance. |
KeyToggleState | Pointer to the EFI_KEY_TOGGLE_STATE to set the state for the input device. |
EFI_SUCCESS | The device state was set appropriately. |
EFI_DEVICE_ERROR | The device is not functioning correctly and could not have the setting adjusted. |
EFI_UNSUPPORTED | The device does not support the ability to have its state set. |

Definition at line 28 of file SimpleTextInEx.h.
typedef EFI_STATUS(EFIAPI * EFI_UNREGISTER_KEYSTROKE_NOTIFY) (IN EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL *This, IN EFI_HANDLE NotificationHandle) |
The UnregisterKeystrokeNotify() function removes the notification which was previously registered.
This | A pointer to the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL instance. |
NotificationHandle | The handle of the notification function being unregistered. |
EFI_SUCCESS | The device state was set appropriately. |
EFI_INVALID_PARAMETER | The NotificationHandle is invalid. |
