WriteConsoleOutputCharacter

The WriteConsoleOutputCharacter function copies a number of characters to consecutive cells of a console screen buffer, beginning at a specified location.

BOOL WriteConsoleOutputCharacter(
  HANDLE hConsoleOutput,          // handle to screen buffer
  LPCTSTR lpCharacter,            // characters 
  DWORD nLength,                  // number of characters to write
  COORD dwWriteCoord,             // first cell coordinates
  LPDWORD lpNumberOfCharsWritten  // number of cells written
);

Parameters

hConsoleOutput

[in] Handle to the screen buffer. The handle must have GENERIC_WRITE access.

lpCharacter

[in] Pointer to a buffer that contains the characters to write to the screen buffer.

nLength

[in] Specifies the number of TCHARs to write.

dwWriteCoord

[in] Specifies the column and row coordinates of the first cell in the screen buffer to write to.

lpNumberOfCharsWritten

[out] Pointer to a variable that receives the number of TCHARs actually written.

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

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