WriteConsoleOutputAttribute info  Overview  Group

The WriteConsoleOutputAttribute function copies a number of foreground and background color attributes to consecutive cells of a console screen buffer, beginning at a specified location.

BOOL WriteConsoleOutputAttribute(

    HANDLE hConsoleOutput,

// handle to a console screen buffer

    CONST WORD *lpAttribute,

// pointer to buffer to write attributes from

    DWORD nLength,

// number of character cells to write to

    COORD wWriteCoord,

// coordinates of first cell to write to

    LPDWORD lpNumberOfAttrsWritten 

// pointer to number of cells written to

   );

Parameters

hConsoleOutput
Identifies the screen buffer. The handle must have GENERIC_WRITE access.
lpAttribute
Points to a buffer that contains the attributes to write to the screen buffer.
nLength
Specifies the number of screen buffer character cells to write to.
dwWriteCoord
Specifies the column and row coordinates of the first cell in the screen buffer to write to.
lpNumberOfAttrsWritten
Points to a 32-bit variable that receives the number of attributes actually written to the screen buffer.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

If the number of attributes to be written to extends beyond the end of the specified row in the screen buffer, attributes are written to the next row. If the number of attributes to be written to extends beyond the end of the screen buffer, the attributes are written up to the end of the screen buffer.

The character values at the positions written to are not changed.

Each attribute specifies the foreground (text) and background colors in which that character cell is drawn. The attribute values are some combination of the following values: FOREGROUND_BLUE, FOREGROUND_GREEN, FOREGROUND_RED, FOREGROUND_INTENSITY, BACKGROUND_BLUE, BACKGROUND_GREEN, BACKGROUND_RED, and BACKGROUND_INTENSITY. For example, the following combination of values produces red text on a white background: 

FOREGROUND_RED | BACKGROUND_RED | BACKGROUND_GREEN | BACKGROUND_BLUE
