参考了示例。

class WOFSTREAM : public std::ofstream

cout<
    
     <<"\n";
    

open(szPath,ios::binary);//注意此处如不指定binary,ostream对象被默认视为对文本进行操作，会额外在行末添加字符：0x0D

this->WriteBOM();

setlocale(LC_ALL,"C");

}

WOFSTREAM& operator <<(const wchar_t* text)

{

const char *pData = (const char *)text;

}

WOFSTREAM& operator <<(unsigned short ch)

{

const unsigned int length = sizeof(ch);

write(pData, length);

return *this;

}

WOFSTREAM& operator<<(WOFSTREAM& (*pfunc)(WOFSTREAM&))

{

return ((*pfunc)(*this));

}

protected:

void WriteBOM()

{

const static wchar_t BOM = 0xfeff;

write((const char *)&BOM, sizeof(BOM));

}

};

WOFSTREAM& endl(WOFSTREAM& wf)//重载换行符

{

wf<<0x000D<<0x000A;

return wf;

}

//使用：

int __cdecl main()

{

if (wf2.good())

{

     <

wf2.flush();

wf2.close();

}

else

{

cout<<"bad!"<

}

getchar();

return 1;

}
