+ WinGopInput.c
+
+Abstract:
+
+ This file produces the Simple Text In for an Gop window.
+
+ This stuff is linked at the hip to the Window, since the window
+ processing is done in a thread kicked off in WinNtGopImplementation.c
+
+ Since the window information is processed in an other thread we need
+ a keyboard Queue to pass data about. The Simple Text In code just
+ takes data off the Queue. The WinProc message loop takes keyboard input
+ and places it in the Queue.

+ Routine Description:

+
+ Returns:
+ 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.
+ EFI_INVALID_PARAMETER - KeyData is NULL.
