如何在WIN32中以新行写入文件API

Question

我试图将数据写入文件。但是，我想以新行添加新数据，但现在我不能。

HANDLE hFile; 
hFile = CreateFile(_T("HELLO.txt"),    // file to open 
    GENERIC_WRITE,   // open for writing 
        0,  // share for writing 
        NULL,     // default security 
       // CREATE_NEW,   // existing file only 
       OPEN_ALWAYS, 
        FILE_ATTRIBUTE_NORMAL, // normal file 
        NULL);     // no attr. template 

// Write to File 
BOOL bErrorFlag = FALSE; 

DWORD dwPtr = SetFilePointer(hFile, 0, NULL, FILE_END); //set pointer position to end file 
LPWSTR data = _T("Data '\n'"); 
DWORD dwBytesToWrite = lstrlenW(data)*2; 
DWORD a = 0; 
bErrorFlag = WriteFile( 
       hFile,   // open file handle 
       data,  // start of data to write 
       dwBytesToWrite, // number of bytes to write 
       &dwPtr, // number of bytes that were written 
       NULL);   // no overlapped structure

Windows使用CR/LF组合来表示行的末尾，你需要写为“\ r \ n”，如果你想换行正确的，例如，记事本露面。
