The FillConsoleOutputCharacter function writes a character to the screen buffer a specified number of times, beginning at the specified coordinates.
BOOL FillConsoleOutputCharacter(
HANDLE hConsoleOutput, // handle to screen buffer
TCHAR cCharacter, // character to write
DWORD nLength, // number of character cells to write to
COORD dwWriteCoord, // x- and y-coordinates of first cell
LPDWORD lpNumberOfCharsWritten
// pointer to number of cells written to
);
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.
If the number of characters to write 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 write to extends beyond the end of the screen buffer, the characters are written up to the end of the screen buffer.
The attribute values at the positions written are not changed.
