-Module Name:\r
-\r
- ConsoleIn.c\r
-\r
-Abstract:\r
-\r
- Console based on Win32 APIs.\r
-\r
- This file attaches a SimpleTextIn protocol to a previously open window.\r
-\r
- The constructor for this protocol depends on an open window. Currently\r
- the SimpleTextOut protocol creates a window when it's constructor is called.\r
- Thus this code must run after the constructor for the SimpleTextOut\r
- protocol\r
