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.
