  _In_  COORD   dwWriteCoord,
  _Out_ LPDWORD lpNumberOfCharsWritten


hConsoleOutput [in]

cCharacter [in]
The character to be written to the console screen buffer.

nLength [in]
The number of character cells to which the character should be written.

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.


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

The attribute values at the positions written are not changed.

This function uses either Unicode characters or 8-bit characters from the console's current code page. The console's code page defaults initially to the system's OEM code page. To change the console's code page, use the SetConsoleCP or SetConsoleOutputCP functions, or use the chcp or mode con cp select= commands.
