WinNtGopThreadWinMain()

DWORD WINAPI WinNtGopThreadWinMain

(

LPVOID

lpParameter

)

This thread simulates the end of WinMain () application. Each Window needs to process its events. The messages are dispatched to WinNtGopThreadWindowProc (). Be very careful since WinNtGopThreadWinMain () and WinNtGopThreadWindowProc () are running in a separate thread. We have to do this to process the events.

Parameters

lpParameter

Handle of window to manage.

Returns

if a WM_QUIT message is returned exit.

WinNtWndBlt()

EFI_STATUS WinNtWndBlt	(	IN EMU_GRAPHICS_WINDOW_PROTOCOL *	GraphicsIo,
		IN EFI_UGA_PIXEL *BltBuffer	OPTIONAL,
		IN EFI_UGA_BLT_OPERATION	BltOperation,
		IN EMU_GRAPHICS_WINDOWS__BLT_ARGS *	Args
	)

Blt pixels from the rectangle (Width X Height) formed by the BltBuffer onto the graphics screen starting a location (X, Y). (0, 0) is defined as the upper left hand side of the screen. (X, Y) can be outside of the current screen geometry and the BltBuffer will be cliped when it is 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.

Parameters

This	Protocol instance pointer.
X	X location on graphics screen.
Y	Y location on the graphics screen.
Width	Width of BltBuffer.
Height	Height 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_GRAPHICS_OUTPUT_BLT_PIXEL)
SourceX	If the BltOperation is a EfiCopyBlt this is the source of the copy. For other BLT operations this argument is not used.
SourceX	If the BltOperation is a EfiCopyBlt this is the source of the copy. For other BLT operations this argument is not used.

Return values

EFI_SUCCESS	The palette is updated with PaletteArray.
EFI_INVALID_PARAMETER	BltOperation is not valid.
EFI_DEVICE_ERROR	A hardware error occurred writing to the video buffer.

		IN UINT32	Width,
		IN UINT32	Height
	)

Change the resolution and resize of the window
