ReadConsoleOutputAttribute function

Copies a specified number of character attributes from consecutive cells of a console screen buffer, beginning at a specified location.

Syntax


BOOL WINAPI ReadConsoleOutputAttribute(
  _In_  HANDLE  hConsoleOutput,
  _Out_ LPWORD  lpAttribute,
  _In_  DWORD   nLength,
  _In_  COORD   dwReadCoord,
  _Out_ LPDWORD lpNumberOfAttrsRead
);

Parameters

hConsoleOutput [in]

A handle to the console screen buffer. The handle must have the GENERIC_READ access right. For more information, see Console Buffer Security and Access Rights.

lpAttribute [out]

A pointer to a buffer that receives the attributes being used by the console screen buffer.

The storage for this buffer is allocated from a shared heap for the process that is 64 KB in size. The maximum size of the buffer will depend on heap usage.

For more information, see Character Attributes.

nLength [in]

The number of screen buffer character cells from which to read. The size of the buffer pointed to by the lpAttribute parameter should be nLength * sizeof(WORD).

dwReadCoord [in]

The coordinates of the first cell in the console screen buffer from which to read, in characters. The X member of the COORD structure is the column, and the Y member is the row.

lpNumberOfAttrsRead [out]

A pointer to a variable that receives the number of attributes actually read.

Return value

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 read from extends beyond the end of the specified screen buffer row, attributes are read from the next row. If the number of attributes to be read from extends beyond the end of the console screen buffer, attributes up to the end of the console screen buffer are read.
