WriteFile()를 사용할때 줄바꾸기(행바꾸기)

The Stupidity of Newlines

In the ASCII table above, there are two bytes that could legitimately be treated as indicating "this line of text is over.  start a new one.":

• 0x0A, '\n', Line Feed.  This is the standard C way to indicate a new line is starting.
  
• 0x0D, '\r', Carriage Return.  This actually moves the cursor back to the start of the line.
  

Sadly, every major computer system nowdays treats newlines differently.

In DOS/Windows, '\r' only moves the cursor horizontally to the start of the line, and '\n' only moves the cursor vertically down.  This means to really start a new line of text in a DOS/Windows file, you need to use "\r\n", like this:

------------------------------------------------------------------------

BOOL WriteLine(CString csLog)
{
    DWORD dwLength;
    CString csPrint;
    BOOL fRet;

    csrint.Format("%s\r\n", csLog);

    fRet = WriteFile(hLog ,(LPCVOID)csPrint, csPrint.GetLength(), &dwLength, NULL);

    return fRet;
}

줄이 바뀌어 파일에 씌어지는군요.
