- Routine Description:
- Retrieves a Unicode string that is the user readable name of the controller

-
- Arguments:
- This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
- ControllerHandle - The handle of a controller that the driver specified by
- This is managing. This handle specifies the controller
- whose name is to be returned.
- ChildHandle - The handle of the child controller to retrieve the name
- of. This is an optional parameter that may be NULL. It
- will be NULL for device drivers. It will also be NULL
- for a bus drivers that wish to retrieve the name of the
- bus controller. It will not be NULL for a bus driver
- that wishes to retrieve the name of a child controller.
- Language - A pointer to a three character ISO 639-2 language
- identifier. This is the language of the controller name
- that that the caller is requesting, and it must match one
- of the languages specified in SupportedLanguages. The
- number of languages supported by a driver is up to the

- ControllerName - A pointer to the Unicode string to return. This Unicode
- string is the name of the controller specified by
- ControllerHandle and ChildHandle in the language specified
- by Language from the point of view of the driver specified
- by This.
-
- Returns:
- EFI_SUCCESS - The Unicode string for the user readable name in the
- language specified by Language for the driver
- specified by This was returned in DriverName.
- EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
- EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid EFI_HANDLE.
- EFI_INVALID_PARAMETER - Language is NULL.
- EFI_INVALID_PARAMETER - ControllerName is NULL.
- EFI_UNSUPPORTED - The driver specified by This is not currently managing
- the controller specified by ControllerHandle and

-Abstract:
-
- This file produces the Simple Text In for an Uga window.
-
- This stuff is linked at the hip to the Window, since the window
- processing is done in a thread kicked off in WinNtUgaImplementation.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.

- displayed. X and Y can be negative or positive. If Width or Height is
- bigger than the current video screen the image will be clipped.
-
- Arguments:
- This - Protocol instance pointer.
- X - X location on graphics screen.
- Y - Y location on the graphics screen.
- Width - Width of BltBuffer.
- Height - Hight of BltBuffer
- BltOperation - Operation to perform on BltBuffer and video memory
- BltBuffer - Buffer containing data to blt into video buffer. This
- buffer has a size of Width*Height*sizeof(EFI_UGA_PIXEL)
- SourceX - If the BltOperation is a EfiCopyBlt this is the source

- used.
- SourceX - If the BltOperation is a EfiCopyBlt this is the source
