- 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.
